The Lumintop Tool was my first favorite flashlight, and I still like them (Massdrop labeled or not). I've decided I don't like using primary cells, reason for knocking a star off. I have the titanium and copper models as well as the brass. The warmer Nichia LED in all 3. The copper was my first and the only one I've used at all as I have gone up in size. Haven't had any issues with it. I don't ever dress up, and I use flashlights all the time, so I've settled on larger lights with larger secondary cells (a 18650 flood mainly, and a 26650 for throw).
