I own a lot of mini LED keychain Lights and I hate forgetting to switch them off with their mechanical switch. then I found this branded (my favorite Brand)Victorinox keychain. and was happy with its electronic 4 minute auto off function , flashing lights and low & high light setting .the swiss cross looks nice too. in fact i bought 4 of these and gave them away as gift. I would've given it a 5 star but when i used it last night inside a movie house the light was dimmer . I havent used it that much since I bought it 4 months ago. so I assume the electronic switch consume electricity when it is not in use. 4 star !

If i was going to pay for it i would not, but i got it for free with a pocket knife so it's ok.

I got this as a free gift from Amazon when I ordered a Swiss Army Knife from Victorinox. Thanks Amazon !!!!!! This is the brights LED mini light I have ever had. It works at high light BLINDING HIGH which is great!!! Also at Low Light good for being discreet. My favorite is the pulsating stobe light which they say can be seen from a mile away and I would believe this. I would have bought this product but Amazon was nice enough to give it as a gift. This is why I shop at Amazon!!!!!
