Can't emphasize enough how great these dumbbells are!
Can't emphasize enough how great these dumbbells, and by extension (pun intended), this expansion set. It allows me to stay healthy with the small amount of time, and space, I have. Thank you again to those that engineered this.

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.
