i have the smaller and the big 10" one (lol couldn't decide on a size #firstworldproblems)
big one is amazing for cruising. small one is cooler but harder to ride. they're so much fun and the douchey feeling you get is a great high.
don't worry about explosions, get an outlet timer and buy a plug with a fuse. they only have problems if you overcharge
pm for hookups, i can help find some made from the blood, sweat and tears of china's finest child slaves
