I never knew this kind of shower hook existed - a real life changer when you are using a liner and curtain. Absolutely love the concept.  I will say that the hooks are a bit light - I would have preferred they be heavier, and the hooks could be a tad bit deeper.  Putting the shower liner on was a little frustrating as when I hooked the hook on the next hole in the liner the previous hole would come off the hook.  But I figured out it worked better to put the shower curtain on first as it was heavier and then put the liner on last.  So not a huge issue.
