Pros: It was easy to put the dumbbells back into set position, also was very convenient.
Cons: Not for serious weightlifters, more for those who cant make the gym
I bought this product and was very frustrated with it. Not only was i spending more time adjusting the weight than actually working out, I felt like my time was wasted purchasing it. If u have the Bowflex Selecttech Dumbbells 552, return it and go get classic dumbbells and workout that way.
