I carried 3 different versions of the Inova Microlight for years, but the last version turned itself on too easily in my pocket. I now carry a Streamlight Nano on my key ring, much brighter than what I used to carry. However, after about 2 years the head managed to unscrew all the way and vanished. Hadn't even depleted the original set of batteries. Otherwise, no issues, and it was replaced with a new model in a different color.
Back to the original question. The light on my nightstand is a Streamlight Scorpion. A gift from a friend several years ago, it's been on a few vacations, and has a hairline crack in the lens, but still works great. The rubber coated body is very easy to grip.
