Every few weeks a version of the same email lands in my inbox, and it’s almost always from someone standing at the same fork in the road. They’ve been training at home for a year or two, they’ve quietly stopped getting stronger on whatever light adjustable set they started with, and they’ve finally decided to spend real money — once — on a set of heavy adjustables they won’t have to replace in eighteen months. The question is nearly always the same two words against two other words: Bowflex SelectTech 1090 or NÜOBELL 80?
It’s a fair thing to get stuck on. On a spec sheet these two look like they’re chasing the same buyer. Both are premium adjustable dumbbells that go heavy, both replace a rack’s worth of fixed weights, both sit in the $700-ish neighborhood, and both promise to be the last set you buy. But they solve the “I need heavier dumbbells” problem in genuinely different ways — one with a plastic dial and a wider top-end, the other with steel plates and a barbell-style handle that’s trying to feel like the dumbbells at your old commercial gym. The right answer depends less on which is “better” in the abstract and more on what you actually care about when a heavy dumbbell is in your hand.
This comparison walks through how they stack up on the things that matter once the novelty wears off: weight range, how you change the load, how each one feels under a heavy press, how much floor and shelf they eat, what owners say about long-term durability, and what you actually pay. If you want the deep-dive on either one on its own, I’ve written full breakdowns of the Bowflex SelectTech 1090 and the NÜOBELL adjustable dumbbells separately. This piece is about choosing between them.
How I Compared These Two
I didn’t approach this as a pure numbers race, because adjustable dumbbells live or die on details that don’t show up cleanly on a spec sheet. Spec analysis shows you the weight range and the dimensions; it doesn’t tell you whether the thing feels like a tool or an appliance in your hand. So I weighted the comparison across six things, in roughly this order of importance for the person actually buying.
First, weight range — both the top end and the bottom. The whole reason you’re looking at a heavy set is that you ran out of room on a lighter one, so the ceiling matters. But the floor matters too, because the same set you press 80 pounds with also needs to handle light lateral raises and rear-delt work without forcing you to own a second pair.
Second, the adjustment mechanism — how you actually change weight, how fast it is, and how likely it is to give you trouble. This is the part that gets used dozens of times per session, so a small annoyance compounds quickly.
Third, build and feel under load. A heavy adjustable dumbbell is the one category where “feels like a real dumbbell” stops being marketing fluff and starts mattering for safety and confidence, especially overhead.
Fourth, footprint — both the floor space and, critically, whether the thing fits on a standard rack or cradle without hanging off the edges.
Fifth, durability, drawn from owner feedback rather than guesswork. Both of these are plastic-and-metal hybrids with moving parts, and both have years of owner reports to learn from.
Sixth, price and value, including the hidden costs — stands, shipping, and the warranty math. With that framework set, here’s how each contender actually performs.
The Two Contenders
Bowflex SelectTech 1090
The Bowflex SelectTech 1090 is the heavy sibling in Bowflex’s dial-adjustable family, the one you graduate to when the famous 552 runs out of room. Each dumbbell adjusts from 10 to 90 pounds in 5-pound increments, giving you 17 settings per hand: 10, 15, 20, and so on up to 90. You change weight by twisting a dial at each end of the dumbbell to your target number, then lifting the handle out of its tray — the plates you didn’t select stay behind.
Spec analysis shows a per-dumbbell footprint of 17.5 inches long, 9.5 inches wide, and 10 inches tall. It ships as a pair with storage trays, carries a 3-year parts warranty, and lists at $799, though Bowflex runs frequent promotions that pull the real-world price down toward the $599–$699 range. Knurled hand grips and an optional SelectTech stand round out the package. The headline number here is that 90-pound ceiling — among mainstream adjustables, very few go higher, and for most lifters 90 pounds per hand is enough load to press, row, lunge, and Romanian-deadlift for the rest of their lives.

NÜOBELL 80
The NÜOBELL 80, made by SMRTFT, comes at the same problem from the opposite design philosophy. Instead of a dial and a plastic shroud, it uses a patented twist-lock handle: you set the dumbbell in its cradle, twist the handle to your chosen weight, and lift out only the plates you’ve engaged. Each dumbbell runs from 5 to 80 pounds in 5-pound increments across 16 settings, and the plates are precision-machined steel arranged in a round, pancake-style stack that closely mimics the silhouette of a traditional fixed dumbbell.
The numbers: each dumbbell measures 17 inches long, 7.5 inches wide, and 7.5 inches tall, with a 32mm knurled aluminum handle and roughly a 4.3-inch grip zone — close to barbell knurling, which is exactly what SMRTFT is going for. A pair nets out around 160 pounds total. It carries a 2-year standard warranty, extendable to 5 years through SMRTFT’s paid SMRTCARE plan, and includes two portable cradles. Pricing sits around $745 direct, and with insured heavy-freight shipping bundled in, the checkout figure often lands closer to $845. It’s also widely sold through retailers if you’d rather go that route — here’s the NÜOBELL 80 on Amazon View on Amazon. Owner feedback is substantial: across more than 1,900 owner reviews, roughly 84% land at five stars, with the praise centered almost entirely on how much the thing feels like a real dumbbell.
Head-to-Head: Weight Range
This is the cleanest split between the two, and it cuts both directions. The 1090 wins the ceiling outright — 90 pounds per hand versus 80. That 10-pound gap sounds small until you’re the lifter it matters to. If you’re already pressing or rowing in the 70s and you know you have more in the tank, the NÜOBELL’s 80-pound cap is a wall you can see coming, while the 1090 buys you two more 5-pound jumps of headroom. For a strong intermediate who plans to keep progressing on heavy unilateral work, that headroom is the entire argument.
The NÜOBELL quietly wins the floor, though. It starts at 5 pounds; the 1090 starts at 10. If you do a lot of light prehab, rotator-cuff work, or rear-delt flyes — the kind of movements where 5 pounds is plenty and 10 is too much — the NÜOBELL covers that range with the same set, where the 1090 leaves you reaching for a separate light pair. Both move in identical 5-pound increments, so neither offers finer jumps in the working ranges, which is worth knowing if you like micro-loading; you’ll want fractional add-on weights for either one.
Net read: if your priority is the highest possible top-end, the 1090 takes it. If you want a single set that genuinely spans from rehab-light to strength-heavy, the NÜOBELL’s 5-to-80 spread is the more complete range for most people, even though it stops 10 pounds short at the top.
Head-to-Head: Adjustment and Feel
Here’s where the two diverge most, and where the decision usually gets made. The 1090 uses two dials — one at each end — and you have to set both to the same number before you lift, or the dumbbell won’t release cleanly. In practice that’s a non-issue once it’s habit, but it’s two actions instead of one, and owner feedback across the dial-style Bowflex line consistently notes that the mechanism does not love being set down carelessly or off-center; seat it crooked in the tray and the dial can balk.
The NÜOBELL’s twist-lock is a single motion: drop it in the cradle, twist the handle, lift. Most people find it marginally faster, and there’s no “did I match both ends” step. The bigger difference is what’s in your hand. The 1090, like all dial adjustables, carries its plates in a wide plastic-shrouded housing, so even at moderate weights the dumbbell is long and the loaded plates sit out away from your hand. It works, but it never quite stops feeling like a piece of equipment. The NÜOBELL’s round steel plates and 32mm knurled handle are deliberately built to feel like a commercial fixed dumbbell — the knurling bites, the balance is closer to center, and for a lot of lifters that confidence is worth real money, particularly when a heavy dumbbell is going overhead. If “feels like a real dumbbell” is high on your list, this is the NÜOBELL’s strongest card, and it’s the single thing owners praise most.
Head-to-Head: Footprint and Ecosystem
The NÜOBELL is the more compact of the two — 7.5 inches wide against the 1090’s 9.5, and an inch shorter in length. That matters more than it sounds, because the NÜOBELL’s profile is close enough to a traditional dumbbell that it fits standard dumbbell racks and cradles, while the wider Bowflex really wants its own trays or the dedicated SelectTech stand to live on without sprawling across your floor.
Both have a stand ecosystem if you want the weights up at lifting height instead of on the ground — Bowflex sells its SelectTech stand in the $179–$199 range, and SMRTFT offers single- and double-legged NÜOBELL stands. Budget for one either way; picking 80–90 pounds of dumbbell off the floor between sets gets old fast, and a stand at the right height is the difference between these being a pleasure to use and a chore. For tight spaces, the NÜOBELL’s smaller footprint and rack compatibility give it a real edge.
Head-to-Head: Durability
Neither of these is a drop-it-and-walk-away tool, and it’s important to be honest about that. Both are hybrids of metal and engineered plastic with moving internals, and both have long-term owner reports that show the same pattern: treat them gently and they last for years; drop, slam, or rush them and the plastic components are the failure point.
Owner feedback on the NÜOBELL is instructive precisely because there’s so much of it. The bulk of the more than 1,900 reviews is genuinely positive, but the critical minority is consistent and worth reading before you buy: a slice of long-term owners report the internal indicator ring or polymer parts wearing or grinding after one to three years of regular use, sometimes out of warranty, and a few flag slow support responses. SMRTFT’s own answer is that the plastic is engineered for the load and that the dumbbells aren’t built to be dropped — which is true, and the same caution applies to the Bowflex. The 1090’s edge on paper is its 3-year parts warranty versus the NÜOBELL’s 2-year standard coverage, though the NÜOBELL can be stretched to 5 years if you pay for SMRTCARE. The practical takeaway is identical for both: set them down, don’t throw them, and don’t expect either to survive CrossFit-style abuse. Within those rules, both have a solid track record.
Head-to-Head: Price and Value
On sticker alone, the 1090 usually comes in cheaper and goes heavier — a combination that’s hard to argue with on a spreadsheet. List is $799, but real-world promo pricing frequently sits around $599–$699, and you get the 90-pound ceiling for that. The NÜOBELL runs about $745 direct, and once insured freight is bundled the checkout number often reads closer to $845, for a set that stops at 80 pounds.
So if you’re optimizing purely for dollars-per-pound and top-end load, the Bowflex wins cleanly. What the NÜOBELL is asking you to pay extra for isn’t weight — it’s feel and footprint: the steel plates, the barbell-style handle, the compact rack-friendly profile, and the build that a lot of owners describe as the closest an adjustable gets to the real thing. Whether that premium is worth it is genuinely a personal call, not a spec you can settle. For a value-first buyer who wants maximum load for minimum spend, the 1090 is the rational pick. For the buyer who has used a plastic-shrouded adjustable before and specifically wants something that feels like iron, the NÜOBELL earns its higher number.
The Verdict: Which Should You Buy?
There’s no universal winner here, but there are two clear buyers. Choose the Bowflex SelectTech 1090 if your top priority is the highest possible weight per hand, you want the lowest price for that load, and you’re comfortable with a dial mechanism and a plastic-shrouded feel you already know works. It’s the better pure-value heavy adjustable, the one that goes to 90, and the safer pick if you’re a strong intermediate who fully intends to keep adding weight to unilateral work for years.
Choose the NÜOBELL 80 if what you care about is how the dumbbell feels in your hand — the steel plates, the knurled barbell-style handle, the compact footprint that fits a normal rack — and you’ll trade the top 10 pounds of range and a slightly higher price to get it. It’s the better pick for tighter spaces, for lifters who want a 5-pound low end in the same set, and for anyone who’s been let down by the cheap-plastic feel of lesser adjustables and wants something closer to the real thing.
If you’re not actually sure you need 80 or 90 pounds yet, that’s a signal worth listening to — a lot of home lifters are genuinely better served stopping at the 52.5-pound class and saving the money. I’d point you to the NÜOBELL vs Bowflex 552 comparison and the broader best adjustable dumbbells guide before you commit to a heavy set you don’t yet need.
Frequently Asked Questions
Is 80 pounds enough, or do I need the 1090’s 90?
For the large majority of home lifters, 80 pounds per hand is plenty — it covers heavy presses, rows, lunges, and Romanian deadlifts for years of progress. The 90-pound 1090 matters mainly if you’re already working in the 70s on those lifts and know you’ll keep climbing. If you’re not there yet, don’t pay extra for a ceiling you may never touch; if you are, the 1090’s two extra jumps are the whole reason to choose it.
Which one feels more like a real dumbbell?
The NÜOBELL, fairly decisively. Its round steel plates and 32mm knurled handle are engineered to mimic a commercial fixed dumbbell, and that’s the single thing owners praise most across more than 1,900 reviews. The 1090 works well but carries its load in a wider plastic housing that always reads a little more like equipment than iron — most noticeable overhead and at the heaviest settings.
Can I drop either of these?
No — and this is the most important rule for both. Each one is a metal-and-plastic assembly with moving internals, and owner feedback on both lines shows that dropping or slamming is the fastest route to a broken unit. Set them down under control. If you train in a way that involves throwing dumbbells, neither adjustable is the right tool, and you’ll want fixed rubber hex dumbbells instead.
Do the plastic parts actually hold up over time?
Based on long-term owner reports, yes — with a caveat. The majority of owners get years of reliable use out of both. A consistent minority of NÜOBELL owners report internal polymer parts wearing or grinding after one to three years of heavy use, and the dial-style Bowflex mechanism is similarly sensitive to careless handling. Treated gently, both hold up; abused, both fail at the plastic. The 1090’s 3-year parts warranty is slightly more generous out of the box than the NÜOBELL’s 2-year coverage.
Should I get the 552 instead and save money?
Quite possibly, if you’re not certain you need to go heavy. The Bowflex SelectTech 552 tops out at 52.5 pounds and costs significantly less, and it’s the right call for beginners and many intermediates. Only step up to the 1090 or NÜOBELL if you’ve genuinely run out of room on a lighter set, or you know on day one that you’ll outgrow 52.5 pounds quickly.
Do I need to buy the stand too?
Strongly recommended for both. You’re lifting 80–90 pounds of dumbbell off the floor between sets, and doing that from ground level repeatedly is hard on your lower back and kills your training flow. Bowflex’s SelectTech stand runs about $179–$199, and SMRTFT sells dedicated NÜOBELL stands. Factor the stand into your real budget rather than treating it as optional — it’s the difference between these being a joy to use and a nuisance.
