These weights are good. Convenient and space efficient. But they are a bit bulky or awkward to use for some exercises. But still a good investment for a home gym, it you're not going to buy a full set of dumbbells.
I use these dumbbells almost every day. They are easy to adjust and hold. My favorite part are the rubbery grips--way nicer to hold than the dumbbells at my gym. Some online reviews complained about the length of the dumbbells, which is long, even for the lighter weight settings. It doesn't really bother me that much, and I'm glad I bought this set.
