The Skilhunt M150 gets AA/14500 right in a way few competitors do, with good modes using either battery type, slim dimensions. ond o lew-veltoge shutoff for both battery types. Add to that magnetic charging for 14500, a high-CRI option, and a magnetic tailcap and the M150 is among my favorites.

The XT12S is a mid-size duty/utility type flashlight with magnetic charging and dual tail switches using a single 18650 battery. It offers shortcuts from off to high and low (or strobe). Its output falls well short of the advertised 1600 lumens, some modes have visible flickering and audible noise, and my sample was not waterproof. The concept isn't bad, but the execution could use some work.
