Title: Too complex and buggy
Review: It took three until I found one that worked - and then it was still buggy. You can't simply press the button and have it turn on. It's a complex set of instructions. Press. Hold. Press again. Hold for a certain amount of time. The next time it *may* remember the previous setting, but usually not. If you just need a simple keychain flashlight, skip it. Too many bells and whistles to be actually useful.
