Now, I am sure I am not alone in using a head torch very frequently, in fact I would say they are almost an essential tool. Currently I have a pretzl tikka+, it produces a decent amount of light and lasts quite well, however I find it a ball-ache removing the batteries to recharge them every other day. Can anyone recommend a good USB-rechargeable LED one? I have been looking at Pretzl NAO but it has auto light sensing that I don't need (or want). all I want to do is just take it off and plug it in to recharge without any mucking about.
