With only 1 in 25,000 being returned then the chance of it catching fire I reckon are small.
I for one do not want to use normal batteries every time as it is a) bad for Environment and b) Bad for the Wallet. so I will risk it.
Means everyone who had one last year had the same risk and chance of it being theirs. Anyone heard of this happening to anyone? Risk is there and risk is small otherwise they would have recalled.
Well if it does catch fire it might make me run a bit faster
From prior reading, re-chargeable batteries, when freshly charged, can display an 'over-voltage' spike. If you were to fully re-charge NiMH's and leave them to stand for 12 - 24 hours, the problem should be avoided.
As I was navigating on leg 5 of Baggin's BG last Saturday, I thought that I'd better have something a bit more 'Kosher' than my botched and cobbled Lucido Coolight 7. So it was down to Ultimate Outdoors in Lancaster and a Black Diamond 'Icon' - a 3W focussed hyperbright LED and 4x 'standard' superbright LED's ( effectively a Myo XP & a Tikka+ in one unit). Needlesport stock them @ £49.99. U.O. have them at £39.99 and I got 10% off against my current YHA card - that's £35.99!
I borrowed a Petzl Ultra for an overnight session back in August. You can read a brief bit about it here: http://blog.irunfar.com/2008/08/orsm-08-in-brief.html . It was absolutely stunning. I was with two other experienced trail ultra runners and we all thought it was obscene. Not sure that it's worth the money, but it's far and away more powerful than any other headlamp I've ever seen. On high, it was literally the difference between night and day.
