Just received the LL7848. I have had a lot of small flashlights in my life. I can find brighter lights (which use special CR123 batteries) and I can find smaller lights (which use button cells) but for the size, convenience and a single, easy to find AA battery I think you have the optimum design compromises between size, battery life, spot size and brightness in the LL7848. This is my pick of most useful flashlights to own. There are plenty of reasons to have other flashlights to serve special needs but this is probably the best general purpose flashlight available. Well done.
