This is the best dry brush I have owned. Place it it about 10-15ft away and clear. As is an "issue" with the other crocs, my feet tend to "glisten" in the scorching heat of the summer (but lets be real they also glisten in the subzero temps)--so the soles of these shoes are made out of the "croc material" and will begin to stink if you dont properly clean, and air out your shoes. I figured I would exchange them for a size smaller but they wouldn?t take them off. After putting up with a falling apart computer headset I decided to spoil myself with a new one and thought i?d Give this one a go. It works well as a charger, my MacBook recognized it without any issues. I have had a pair of aerosole shoes with these soles before and they wore completely through within 2 months. I?ve used these for a few times only. She raved about them for months. They also auto disconnect when put back on the charging cradle.
