I own two sets of the Pro (plastic) version of these adjustable dumbbells and have had a great experience with them.
They pair well with the 2.5lb, 5lb, and 10lb change plates I already own. Despite the plastic construction, I find them sturdy when loaded; there's no risk of them unscrewing during movement.
I enjoy the handle diameter and plastic knurling, which are much better than I expected and mimic the feel of fixed dumbbells. They feel good.
When I use them:
-Single arm or movements to avoid the cage of an adjustable
-Make up additional pairs of dumbbells for drop sets (I don’t see myself buying fixed dumbbells anytime soon)
-Making up additional dumbbells for the kids
Things to know:
-Slow to change, I wouldn’t want them as a primary or my only pair
-Durability, they are plastic, imo, they should be treated like it.
Overall, I think they are great value for what they are.
