Oh boy.  The cover is difficult to release because of the thin lift tab.  You definitely need good wall secures, not the meager screws included.  The stick tape pad ---nah.  So, if you're a renter, take heed!  Overall, we were disappointed because it wasn't more user-friendly for a family, especially with the brushes coming too close to the light strip, which isn't easy to clean around. The brush holder unit was a bit loose, so some tweaking is needed here. Note: You MUST have the brush dry before placement.  Who wants to be "Brush Monitor"?!  Also, we wished there was an electrical cord/charger option, but decided to give it a try.
