Pros: Inexpensive Different colors available so kids don't fight over who had the controller - they are assigned colours/patterns Long battery life - several days between charges easily - use moderately. Cons: When the battery is very low, the controllers shake a bit. My son plays Minecraft and when the battery is low he moves left or up like he's holding a joystick. The solution is simple enough - charge it up. Update 18 months later: they still work great! Very happy with them as they have withstood abuse from 6 and 3 year old boys.
