Received OTR M3 Pro this week (less than 20$ with a coupon from banggood).
Comes with a Usb type-c charging port (not really a fan of it) and options for cw or nw. You can use the port for charging or as power for the light (no battery) if that’s your thing.
It’s very light and small, nowhere near my Astrolux S41. Also beware as the barrel won’t accept 18350 batteries, they are too thick for it.
The ui is good and the magnet tail comes handy. I’m considering putting a LH351d for high cri.
