Is the NÜOBELL 80 worth it over a fixed dumbbell set?

If you need 5 to 80 lbs per hand in a small space, one pair replaces 16 dumbbells and adjusts in seconds. At $515.99 at MAGMA fitness as of November 3, 2026, it costs less than a full rack of comparable steel dumbbells.

How does it compare with the 50 lb NÜOBELL?

The 80 lb version adds 30 lbs per hand and more settings, at a higher price and a heavier footprint. Choose the 80 if you press or row above 50 lbs per arm; the 50 is enough for lighter training.

Can I drop these dumbbells?

No. The twist-lock plates and polymer parts are not built for dropping, and drops can damage the mechanism and void the warranty. Set them down on the cradles.

What comes in the box?

Two dumbbells, two portable cradles and a quick-start guide, with a 2-year warranty that can be extended to 5 years through SMRTCARE.

When is the best time to buy?

Adjustable dumbbells usually dip during Black Friday and New Year sales. The current $515.99 at MAGMA fitness as of November 3, 2026 is already well under the set's usual $700–$800 street price.
