I carry a Streamlight also, just a way different one,,, the Nano.Don't have much call to use it regularly, just walking from the house to car and back if needed. Bright enough to show the way. Only on my second set of batteries.
Badge awarded. I like to carry a small light and a light with a little more oomph. The RovyVon A5 is always with me. The S1R is one I grab among others for the extra power.
I had one of those Streamlight Nanos years ago. Same as you, used it every once in a while. One day, went to grab the keys and half the flashlight was missing. I guess it had unscrewed itself at some point.
I thought of that and put a layer of Teflon tape around the threads. Seems to be working well as the cap is still tight.
I carry one or both of these every day
Is that MicroStream the rechargeable one or the one that takes AAA's?
