Strengths & Weaknesses

NÜOBELL 80lb Adjustable Dumbbells

+ Strengths
  • BarBend recorded no stuck adjustments and rated the twist dial the easiest to use
  • Strong Home Gym called it the smoothest, most natural feel in the test
  • Took two outright Best Overall awards, from BarBend and Garage Gym Lab
Weaknesses
  • Garage Gym Lab noted the plastic components and lack of any drop protection
  • At 845 dollars a pair it is among the priciest mainstream options
  • The handle shape feels uncomfortable to some lifters per BarBend
Key flaw: The NÜOBELL is not built to be dropped.

Bowflex SelectTech 552 (Results Series)

+ Strengths
  • Fitness Volt ranked it the outright top pick at 4.7 out of 5
  • Fine 2.5-pound increments make it forgiving for beginners and small progressions

Weaknesses
  • Reviewers rate long-term durability below the all-steel competitors

The Verdict

Our Bottom Line

The NÜOBELL won because it is the only set to take two outright Best Overall awards, from BarBend and Garage Gym Lab, and it earns them on the things you touch every rep. The twist-handle dial is the fastest adjustment in the category, and BarBend reported it never stuck during testing. Strong Home Gym went further and called it the smoothest-feeling adjustable it has used, with a balance and shape closest to a fixed dumbbell. That combination of speed and feel is the whole point of an adjustable set, and the NÜOBELL nails both. For a home lifter who wants one pair to replace a rack and barely notice the difference, it is the clearest pick across all six expert sources we synthesized.

Bowflex SelectTech 552 Adjustable Dumbbells (Results Series) hero view

The Bowflex SelectTech 552 wins value because it delivers the adjustable-dumbbell experience for less than half the price of the NÜOBELL. Fitness Volt ranked it the outright top pick at 4.7 out of 5, and BarBend, Garage Gym Lab and Men's Journal all reached for it as the friendliest set for a new lifter. The dial is clearly marked and quick, and the fine 2.5-pound steps make small progressions easy. The current Results Series also resolves the plate-dislodging recall that hit older 552 units. At around 344 dollars it is the lowest-risk way to find out whether adjustable dumbbells fit your training.

Best for:
  • You are new to adjustable dumbbells and want the lowest-risk entry
  • You want fine 2.5-pound increments for small progressions
  • You are working to a tight budget
  • You prefer a clearly marked dial over a switch or pin
  • You do not plan to drop the weights
