    bright when you can turn it on
    lights up great and the ring selector works well. the berries and cherries effect is nifty but the red is useful. advertised to stand up so it has a recessed button. without any recesses around the ring tho it is hard for me with Large sized gloves to depress the button confidently. this seems to not be an issue on the mh12 or p12 lights also one of the pocket clip bolt holes was too large. only one only one allen bolt was holding on the pocket clip. if the button wasnt so hard to actuate id give it more stars. the pocketclip thing is probably not a thing, but trying to turn it on is.
    Prosbright and infiniteally adjustable red light blue light berries and cherries strobe takes AA and 123 it stands up on a very level and sturdy surface
    Conssos & becon (anyone have stories of those light features ever being actually used?) completely recessed button is a chore to turn on one handed, i mean i should only need one hand right? is stupid as a standup candle, falls over, shines right in ur face. if turning it on doesnt bother you all its other features really are good
