Hi, I got 2 Super Slicks and as the other members have noted, the battery life did last for near 20 minutes after only 45 sec. charge...but this only lasted for about the next 3 charges (completely empty before recharging), diminishing each time and significantly short battery life of 2 minutes by the 4th or 5th charge. I opened the second car and checked to see if the car already had some battery life in it before charging (which meant that I was double charging before, which would explain the longer first run) and it did--and soon followed the same drop in battery life after 4 charges. They are equal in battery life around 2 minutes. This could be my cheap rayovac batteries which are not totally new to begin with--but I'm just wondering what some other people's experiences were after 10 charges later...
I also bought the 2F2F purple motor kit but it'll probably die after like 1 minute with the battery situation I have currently.
As it is, my Bit clones last longer.
