Thanks to the PWM there is no tint shift from low to high...very nice. The threads are a little gritty but not bad. The O ring makes it harder to turn more than anything else. Not a problem really given the excellent knurling, the best of my meager collection.
I don't care what anybody says about the lettering, compared to the "subtle" labeling of the ld01 the mini looks like a top notch, first class rock star!
Okay, technically not Quark Mini's , but the Raw is tiny & the SPY is small for a 2 cell light.
The Raw Ti has the SST-50 in it. Very bright indeed, so I would call it a blaster.
