I have all the Led Lensers. Im sick of them now, really hate the lack of regulation on earlier models. Best one and only one worth having is MT7. Throws almost like TK41 floods almost like TK41 but can only do one of the above chores at a time. Also, expensive on batteries and brightness drops off with regulation after 2 minutes and doesn't help to turn it off and on again
. Glass breaker on bottom is cool and a good self defense tool. Too bad the light slips out of your hand if it's cold so easily. I was the biggest LL fan,
until I discovered real quality lights. My X21 sits in its case in storage.
