Back in the day I had an LM31 and LM33, and bought a couple LM31s for family members. Those were nice simple lights which worked well. I also picked up a D-Mini Digital and it was pretty cool, too. Solidly built, good throw, all in all a good light. Of course they got flipped in favor of "newer and brighter;" you know how it is.
But I then went through 3 different "improved" iterations of the Incendio which drove me absolutely nuts. Either the UI was wonky, or the reflector wasn't matched to the LED, and the resultant beam pattern made the old Cree XR-E ringy beams look GOOD. Got rid of those and was off LP for a couple years after that.
I did pick a used earlier model Incendio off the MP for a spare light a month or so ago, and aside from the cool tint, I like it. Fit and finish are good, it's solid, the clicky is tad mushy but the UI is simple 3-level and works, and the beam profile is OK.
I might go back and give the "new" LM31 or 33 a try, but I'm still a bit hesitant.
