Bests & Worsts Reviews from Amazon

I've needed a small flashlight for quite a while, as our backdoor is not well lit. I thought I would get a small single AAA flashlight, and found a very bright one for just under $50 (Fenix-made). However, after reading the reviews on this one, I decided I couldn't go wrong with trying the Nanolight. This light may only be a 10+ lumen, single-LED light, but it is brighter than a 9 LED light we bought at a hardware store (for $2) that requires 3 AA batteries. Amazingly, this is so small that it is barely half the length of my thumb and more thin than any point on my pinky finger. It has a nice clip that fastens it to your keychain in a snap. I bought one for myself and my wife, and we use it in place of any light in our car. With new LED technologies just around the corner, why pay more for other, expensive LED lights when you can get this for so little and choose to upgrade later if needed? We will be buying a lot of Nanolights for Christmas later this year. It is water-resistant, powerful, and always there when you need it without taking up room in your pocket. There are two drawbacks. One is replacing the four tiny alkaline batteries (using the same size hearing aids use). Fortunately, the cells are pretty cheap and the light is supposed to last up to 8 hours on a set. The second drawback is that the light has a real tendency to fall apart the more it is used. However, there is a fix for this. Simply put Teflon tape on the threads.. This will keep it waterproof while assuring the bezel can't easily work itself loose. Once you get it, you will wonder how you got along without it. UPDATE: I've found out that the hearing aid batteries that work in this light are zinc-air batteries. They work, but they require access to air, which means when the batteries exhaust the air in the waterproof casing, they stop working. You need to unscrew the top and let it set for a minute or two to get the full charge back. Please search Amazon for bulk LR41 batteries--you will find them so inexpensive that any concerns about availability or pricing for replacements will fade away. These are alkaline batteries, so you won't have the problem I mention above.
