Bought the R1 as a gift for my son for christmas. Not really used the board yet but 1st impressions are good. Excellent communication via e mail. Good sturdy board. Fast delivery once in stock. Only one downside, the board beeps when you get on and off it. Which cant be turned off. It was beeping like crazy when i had a quick turn as i couldnt do it. But i'm sure it will be fine when ridden by my Son who is able.
