The lights are easy to install, shine bright and the battery lasts long enough. I am specially fond of the battery status feature that is missing on some other torches (not e-skate related); after turning the light off, special LEDs shine for a few seconds, to let you know how full the battery is.
I thought i don't need bluetooth control but i was wrong. It would be well worth paying those extra 10 eur for BT conectivity. Seeing new skate models equipped with integrated front lights is definitely step in the right way, well done B-ONE!
Probably the best 2 in 1 board in this price range, has everything you need. Definitely recommend to buy.
