I have an off brand 40kg version in my home gym, so far very happy with it. I have not enough space to place a dumbbell rack not will to spend so much money. I had the clamp on kind of adjustable weights, but the clamps gave up sometime so I dropped using them for a while in favor of barbell only. Now that I have those I use them frequently.

TLDR: they're worth it.
