I've had the one cell joystick and now the two cell race for the last two and a half years and would advise caution
they're brilliant lights, bloody bright, very compact, very practical, very durable, the mount on the joystick is a tad weedy, the one on the Race and upwards I presume is rock
that said, I've now returned four under warranty, all for failures at the charger or switch, it's such a shame because it's a superb light but it's desperately annoying when you can't charge it or switch it on/off
the race I have now, the third one, has lasted a year but now the switch is getting very playfull and has to be pressed in exactly the right spot to cycle through the modes/switch on/off
they were nice as pie about replacing the duffers but seemed to just send me back someone else's repaired one every time, one was a deader when I opened the box
perhaps the newer models are fixed but the one playing me up now is only a year old and was a certainly a new model at the time, BM has one and doen;t grumble so perhaps I've just been very unlucky ...
the two cell has plenty of power for commuting on the excellent pulse setting, perhaps even too much, I get the odd grumble and on full whack it certainly lights up the road nicely, the higher power models I can only imagine havng applications on off road
