Disadvantages:
- The silicone shell of Remotes needs from, so that they fit into the receptacles;
- It will be installed AAA battery pack with charging contacts, 700 mAh, but it has presented by capacity, I run my two Remotes alternatively with Ni-MH AA 2400 mAh batteries. They were charged by myself last about 4 weeks ago and are still as a 3/4-full display. Of course, the gambling behavior of my children: no more than 1 hour a day.
So, my conclusion: the idea is nice, but totally overrated. Still I have to say, my copy smelled relatively badly burned ("electric"). Have the charging station and not keep it but then returned to the dealer.
