I bought this BC30 V2.0 & have been riding it for 8 weeks... Here is my review(I love it):
- : plastic handle bar harness (plastic will become brittle over the years and will end-up breaking)
- : beam too wide, not focused enough for a transportation light. Also the beam is symetric, ideally it should cut sharp horizontally to avoid glare for incoming traffic
Huge + : The ability, at a press of the wireless switch, to flash at cars that forgot to turn off their high beam and are blinding you.
+ : The general build quality. It's almost all solid aluminium, no plastic. The only plastic (at risk of breaking after a few years) is the handle bar attachement.
+ : The ability to swap the batteries. No obsolescence due to embeded battery worn-out. Be careful about the battery type though: 18650 with the longest length available : 69mm. I use some keepower protected (68.8mm length)
Overall I am very happy after 8 weeks
