Bests & Worsts Reviews from Amazon

First off, let me say that the build quality on this little light is fantastic. I've had mine since 2011 and it still works great. Very bright, super small, and always with me on my keys. It's been invaluable for me in a lot of situations and I've only replaced the batteries once. Now the bad part: the cap randomly come unscrewed on its own. Once it came apart in my pocket, which wasn't really a problem since it was able to recover all the pieces. The second time, it came apart at some point while retrieving my keys from my pocket in my gravel driveway. I noticed it was missing a few days later and had no idea where the parts were. Luckily, I was able to find the head and all the batteries in the driveway almost two weeks later, after noticing a reflection of light off one of the batteries. Everything had been rained on, there was grit all over the threads and there were gouges on the head (I'm pretty sure it had been ran over at least once). I quickly wiped the grit off the threads, screwed it back together and went on my way. I believe the residual grit on the threads actually improved things, as the head has never fallen off again. It's been over three years and everything has stayed together with no issue. The head is still easy enough to turn with one hand, and the rain, grit and being run over seems to have had no effect on it. Overall, it's a great light, but only if you can make sure it doesn't come apart. **UPDATE - 12/8/2017** Well it's been almost three years since I first wrote my review on this and it's still going strong. I believe I've changed the batteries once since buying it back in 2011. It's been on my key ring continuously for almost seven years now and it still works like a champ. I have no issues with the head coming loose or falling off anymore since the initial incident, so I anticipate having this on my keys for another several years.
