I just got mine in the mail this past weekend. First impressions: It's tiny and bright bright bright (using 18350). Build quality is good. They give you a nice holster (though I wonder about the durability, material seems thin.) There needs to be a level somewhere between the ultra-low of 1 lumen and the next level which is 70 lumens. (30-40 lumens would be nice.) On Max it gets hot quickly. Very quickly. The secondary red light is useful, but due to it's location in the reflector, the beam pattern is... odd to say the least. The strobe modes are nice,(especially the beacon and SOS) though I'm hoping they don't get much use. So far, it's fighting for the daily spot in my pocket with my ArmyTek Tiara C1v2 with no clear winner yet.
