Review: 100 lumens for it's small size? absolutely amazing! literally pocket friendly!
Review: This flashlight is tiny. Fits perfectly in the coin pocket in my jeans. I work in IT in a manufacturing plant, and a lot of IDF's are in the ceiling with no lights. This flashlight brightens the entire compartment. When you have to dig through hundreds of patch cables to trace out a line to a wall drop in a pitch black room, you'll be happy when you have this in your pocket. It comes with a AAA Heavy Duty battery. I've always heard bad things about Heavy Duty batteries, so I've always used Alkaline or NiMH. The flashlight last 8+ hours on that single Heavy Duty battery. Because I have so many NiMH AAA batteries, I won't be purchasing any more Heavy Duty batteries, but if you don't already have other batteries, you can save a few bucks by just sticking with the same type the manufacturer includes: the Heavy Duty type. Before purchasing this flashlight, I never had anything small enough to fit in the coin pocket on my jeans, so I never used it. With that being said, the first time I washed my pants after purchasing the flashlight, I forgot to remove the flashlight from that coin pocket. I didn't realize what I had done until after I took the jeans out of the drying machine. Still works like a champ. No damage what so ever. I'm a flashlight junkie (power goes out often where I live), and if I didn't have so many already, I would definitely purchase this product again.

Pensé que era un poco mas grande, si debes llevarla en algún llavero o guardarla bien, es muy pequeña y fácil de perder, ahora a pesar de su tamaño da muy buena luz, si quieres una lampara muy pequeña que alumbre bien esta es tu opción
