The Cube Club Dumbbells adjust smoothly from 5 to 52.5 pounds when you turn dials. With 2.5-pound increments for the first 25 pounds (and 5 pounds thereafter until you get to 52.5 pounds),
These sturdy dumbbells allow subtler load adjustments, but their length can make some exercises more difficult, and the weights don’t feel as sturdy as our top pick.
Seeing both dumbbells on an eye-level, they both seem to appear coming from the same factory. It is very difficult to tell which would be much practical until we hold them in hands.
Though the price of both the dumbbells is the same, you can go with anyone which seems best after reading this comparison or which appeals better to your eye.
cube powerbells have an edge over the flexibell in specifications. Where powerbells offer a 1-year service and replacement warranty, Flexibell only offers a warranty for 6 months. (Warranty don’t cover accidental damages, or simple wear or tear)
It's just the brand’s trust, which makes me buy Flexibells. Flexnest appeals me more than anything. Watch my full review on Flexnest Flexibell here:
