1) It allows you to dry hands-free, which means your arms won't fall off and you can multitask when you're short on time.
2) It adheres to the wall without hardware, so minimal effort is required to install, and you won't have to spackle after.
3) Since it's wall-mounted instead of on a stand like other hands-free dryer holders, you still have maximum sink-top space for all your brushes, bobby pins, and other junk.
4) It's $9.99. You can't even get a decent pizza for $9.99.
