I am on my second set of power hooks. I like them. They do take some getting used to. You have to be careful how they sit in your hands or the bar that connects the two side can dig into your palm. The reason I am on my second set is that the bar I mentioned above can break at the wield.
If you are not careful when you drop a dumbbell you can break the wield. If you know how to wield you could probably fix a break. I use them with plate loaded dumbbell handles and I think they are well worth the money even if I have to replace them every couple of years.
