These are some of the most useful things in my gym. I never used to do much dumbbell pressing because the process of getting them into position always felt very dicey and unsafe, especially when going heavy (or as heavy as I could go, anyway.)
Now, there's definitely a learning process to using the dumbbell hooks and you need to dial in the right height well, but once I got the hang of them, I really started appreciating them. Build quality could be better though, the paint chips off pretty fast.
