Quick verdict
The NÜOBELL 5–80 lb adjustable dumbbells pack 16 traditional dumbbells into one, with fast, twist-to-select adjustments, solid metal plates, and a compact footprint — an excellent pick if you want a near-“fixed-dumbbell” feel without building a rack. They’re especially strong for home-gym users who want quick changes during circuits or supersets and for lifters who need up to 80 lb per hand.

Weight range: 5–80 lb per dumbbell (16 settings: 5, 10, 15 … 80 lb).
Increment: 5-lb steps.
Dimensions: ~17″ L × 7.5″ W × 7.5″ H

Why you might buy it
- Space saver: Replaces 16 pairs in the room of one set — excellent for apartments and small home gyms.
- Speed of use: The twist-select mechanism is among the fastest on the market — great for circuits and drop sets. Reviewers repeatedly call NÜOBELL one of the quickest-adjusting sets they’ve used.
- Build that feels like real plates: Precision-machined steel plates and a knurled handle give a close-to-fixed-dumbbell feel (heftier and quieter than many cheaper plastic/iron hybrids).
Pros
- Fast, intuitive weight selection — transition times are short so you don’t lose workout momentum.
- Solid feel: steel plates + knurled handle give a “real weight” sensation.
- Compact footprint — replaces a full dumbbell rack.
- Good warranty & manufacturer support (2-year limited, with some direct-purchase extensions).
Cons
- Max 80 lb per hand — superb for many users, but advanced lifters who need heavier single-arm loads may outgrow it.
- Price: premium adjustable sets aren’t cheap; price can vary and occasional promotions/coupons appear. (Compare before buying.)
- Still not invulnerable to drops — warranty excludes damage from slamming or dropping, so treat them like precision tools.
Performance & real-world use
In daily workouts — presses, rows, single-arm movements, curls, goblet-style work — NÜOBELL performs like a traditional fixed dumbbell set in both balance and feel because of its steel plates and knurled handle. The standout here is the adjustment system: dozens of independent reviews and hands-on tests rate NÜOBELL among the fastest adjustable systems to change weights, which makes them ideal for superset-heavy programs and HIIT-style strength circuits.
Comparison
- NÜOBELL — feels closest to fixed dumbbells thanks to steel plates and knurled handles; fast twist selection; strong warranty; capacity to 80 lb.
- Bowflex SelectTech (e.g., 552/1090) — widely available, many models have plastic/shuttle design with cam-style selection; often slightly noisier and with a different feel; some Bowflex models offer higher max weights depending on model.
- PowerBlock— compact and rugged, often used by serious home lifters; different selection feel (pin system) and usually more modular for higher-capacity upgrades.
- Choose NÜOBELL if you want a steel-plate feel + quick dial changes. Choose PowerBlock or heavy fixed plates if your primary goal is highest possible capacity and industrial-grade longevity.
Who is this best for?
- Home gym owners who want the look/feel of fixed plates but the space savings of adjustables.
- Lifters who do a lot of supersets/circuit training and need fast changes.
- Beginners → intermediate lifters progressing up to 80 lb per hand.
Avoid if:
You regularly need >80 lb per hand for single-arm heavy work or You plan to slam or drop weights frequently — warranty excludes impact damage.
Short buying checklist
- Weight ceiling: Will 80 lb per hand be enough in 6–12 months? If not, consider higher-capacity options.
- Seller & warranty: Buy from an authorized seller or the official store for warranty clarity and possible extended coverage.
- Price & deals: Check current price/promotions — coupon/discounts sometimes available on Amazon or official site.
- Space/stand: Confirm footprint fits your bench/training area and consider a stand if you want them off the floor.
