Not so waterproof
This brush worked really well for a while, but it didn't last very long. I purchased this in late November of 2016, it is now March 2018 and it no longer works. I attribute this to water damage, as when I opened the battery compartment the batteries were rusted over. I'm not sure exactly when it stopped working but I know it was around the beginning of the year.... meaning this item bearly made it over 1 year....
