NÜOBELL 580 vs PowerBlock Elite USA
Which should you buy? Our verdict on both, pulled from our full Best Adjustable Dumbbells: 4 Sets Compared (and One to Skip) comparison.
The NÜOBELL 580 wins for most people because it changes weight instantly and feels the most like a real dumbbell, and it's worth its premium. The PowerBlock Elite USA is the value and durability pick, with an all-steel build that grows to 90 lb. Choose the Ironmaster if bombproof metal matters more than speed. Avoid the original Bowflex SelectTech 552: it was recalled for plates dislodging mid-lift, so buy the reinforced Results Series redesign if you want that dial.
NÜOBELL 580
Buy itThe closest an adjustable gets to a real dumbbell: fast, compact, and worth the premium.
- Twist the handle and the weight changes in one motion, with no separate dials or pins to fumble
- Round dumbbell shape and knurled 32mm aluminum handle that feels like a fixed bell
- 5 to 80 lb per hand in one compact unit that replaces 16 pairs
- Reinforced polymer shells mean you can't drop them without risking damage
- Premium price, and the 80 lb version is a real jump over lighter sets
PowerBlock Elite USA
Buy itAll-steel, endlessly expandable, and the best value if you can live with the blocky shape.
- Welded steel plates, a knurled stainless grip and few moving parts, which reviewers rate among the most durable designs here
- Expands from 50 up to 70 and then 90 lb per hand with Stage 2 and Stage 3 kits, with a 5-year residential warranty on handles and plates
- Small footprint and a magnetic selector pin that's quick to set
- The square cage shape feels unnatural and can catch your wrist on some movements
- Pin-and-adder adjustment is a step slower than a single dial or twist
