Works nice at night doing geocaching to follow a UV trace.
The rubber of the tail cap was not in it's place but easy to repair.
I measured at about 3V a consumption of rouhly 300mA which makes about 1Watt! Even at 3,7V -like a LiIon battery- I could measure the same power. Definitely no 3W lamp!!!
Could be worse but in the end it's ok. I haven't looked but my guess is that a torch of this type would've cost much more in Germany.
works well for my purpose (geocaching) but could've been more powerful.
