Nuobells

I have the Nuobell 550 and I am in love with these dumbbells. They are amazing and compare to other brands, these are compact and are the closest to regular dumbbells. I bought the expansion kit, just in case I ever get strong enough. With all the stuff going on with Tariffs, and possible price change and also availability, i thought it best to buy the expansion kit. I rather have it and not need it, than the other way around.

Quality company, quality product

I love that NUO offers an 80lbs expansion, instead of forcing you to buy a whole new set. I was able to keep the original handles, and add the new plates in just a few minutes.
