My kid will use them off and on throughout the day and I havent charged them once since we got them 4 days ago. We have 2 so that we always have something on the bed and I prefer the Beckham for breathability and protection. The scroll wheel is zowie 16 click. All parts were in the nicely packaged box and all predrilled holes lined up. Bought for my 11 year old son for remote learning back in August. The toebox is the perfect size as is the width of the slipper. Exchanging was super easy. 2) Gorilla Grip does stay in place. I found the mickey hands here on amazon as well and purchased 2. I love, love, love the charging port.
