NÜOBELL 5–80 lb Adjustable Dumbbells — Best Overall
NÜOBELL dumbbells are often called the “Ferrari of adjustable dumbbells.” With a massive 5–80 lb range, they replace a full commercial rack while maintaining the feel of traditional steel dumbbells. The adjustment mechanism is lightning-fast — just twist the handle to change weights in seconds. The steel knurled grips feel premium and provide excellent control for heavy lifts.
Key Specs
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
Handle: 32 mm knurled aluminum steel-style handle (barbell-like grip zone).
Materials: Precision-machined steel plates + reinforced polymer cradle and aluminum connectors.
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.
