I've had this for almost a full decade now, mounted on my MR11 rail, it's been on my carry gun every day, it's survived being worn while hunting, competitions, and daily carry. From being dropped, submerged in water, used as a standoff device, and survived through at least 10 thousand rounds through my pistol.
I'm proud of this light for surviving as much as it did over 10 years.
The battery compartment finally broke after I made a hard stop on a VTAC barrier, I didn't notice it until I went to change the batteries, but it still works (although not as waterproof as it previously was) and I still carry it to this day.
