I'll be honest. I bought a cheap off brand version of these and returned them because they were almost impossible to change the weight increments. I got these Bowflex weights and they are very smooth to switch between different weights. Worth the higher price for something that functions smoothly.
As a healthcare professional, I have little time to exercise. I have found the 552 dumbbells and stand to be easy to use, and the app is excellent with motivating me to continue to utilize. Would recommend it to others!
Pros: Comfortable, Easy Storage, Easy To Use, Quiet, Strengthens
