Great Flashlight - Dangerously bad holster.

OG Klarus FanBoy since the XT1A (still have it, still works). Wanted the output of the XT21X Pro for my current job - lots of time alone covering large areas at night. I leave it set on tactical mode with the side switch pre-set to a lower lumen to light up the immediate area so I don't trip over things, but can instantly go to turbo mode with the tail switch to reach out and cover a larger area - it has a fantastic mix of spill and throw. And the ability to go directly to strobe with the secondary switch has a very motivational effect on crackroaches and methbillies that prevents me having to do something that would result in paperwork.

The holster, is a different story. It's a pro-active hazard. The cup at the base of it tends to catch the edge of the base of the flashlight. Then when I get back in the vehicle, it can shift and activate the strobe. Because I wear a heavy jacket (I'm in Canada, and it's cold up here), I don't see the light getting activated, and the first I know about it, is from the smell of the melting nylon of the cover flap. After having this happen a few times during the first week of use, I ditched the holster it came with and went with something after-market. Some people would say that this is a "me" problem and it's a training issue, but on a 12-14hr patrol, in and out of the vehicle a dozen or more times a night, no matter how much I tried to pay attention, fatigue happens, and it was way too easy to trip off this failure mode. Searching some of the forums online, this is a known and fairly common problem that people have had with this holster.

Klarus can fix this by making the protective cup at the base an inch deeper so it's far more obvious when the base isn't seated fully, and having the top of the cup flared out to reduce the chance of it catching in the first place.

Still love the light itself, though. It really fits exactly what I need for an EDC tactical light for patrols.

Customer Service

Overall the light is fine. BUT, customer service is a significant problem. Light will not work with 18650 battery in the adapter sleeve. Inquiries to both Klarus store result in responses seeming to be designed to be difficult to receive satisfaction.
They want proof of purchase - seems obvious since I bought it direct.
They want a picture of the model series of the light - also obvious.
They want a VIDEO to show that the light won't work with the battery and adapter - what is there to show$

Not at all happy with the company
