I obtained 2 of these lights. Both led lights failed after about 1 month. The great thing is that they have a lifetime warranty. Bad thing is I sent them to manufacturer (Victorinox Swiss Army) in for warranty repair/replacement of lights 10 weeks ago with no response from manufacturer. I emailed them and got an auto response that someone would be getting back to me shortly,...has been 12 weeks with no contact. Called manufacturer 6 weeks ago and they took my number and told me someone would get back to me, to this date no one from the manufacturer has contacted me. I would suggest that if you want a LED flashlight go with another brand. I hope that the Swiss army does not use these lights because they will be out of luck.
