Great light. I love the full power momentary option. The quiet switch was a good idea. I wish it took a longer press or a tailcap turn for constant on. Press and hold for three seconds is odd to turn it constant on. I found that I could press and hold for normal momentary use for more than 3 seconds and still want to turn it off quickly. Shouldn't have to press and hold for three seconds to turn it off.

The quiet click does not seem like it has much utility. The recessed tail cap is more of a bother than what it is worth. I do not worry about accidental activation. The recess makes it difficult to activate.

Great light for every day carry, functions are easy to use, good beam throw with broad illumination.

Love this light if you have a quick thumb there is no issue.

Other reviewers have pretty much already hit the nail on the head with observations regarding the nature of the tail switch and modes of operation. The light's 'menu' is awkward and different enough from most lights of this type that if you don't use it regularly, you may well forget how to work it. The having to hold the switch to activate/deactivate it makes it hard to really get short momentary use out of it. I can see why Klarus discontinued it. That being said, it is a well-built, quality light that also looks great and the output is very good, like other Klarus lights. Someone else said they wish Klarus made a replacement tail switch in a regular design. That would be great. I do not regret buying the light. I got two of them on the sale price and they will be kept as spares and/or for go-bags. Another issue that was raised was the fact that there is no memory, and the light comes on in highest output every time. This has been a 'feature' of many Klarus tactical lights from the get-go, and is ok if you are out on the street and will need it to come on in the high mode every time, like a policeman or power company worker might. It is awkward otherwise. It precludes using this light for your night stand - way too bright for in the house on the high setting (it will blind you if you wake up and turn this on in the dark). The others I own fit into the same category, but this one has the added detractor of the having to hold down the switch to activate/deactivate. I have a Terralux TT4 which also comes on in high mode every time and has virtually the same switch as the other Klarus lights like the XT11. Such lights are relegated to outdoor use only, or for very large indoor spaces like a warehouse, etc. Since this light is discontinued it's a moot point, but if you come across them for cheap price and you want it for your only light, do not buy it for keeping in your nightstand. Think of it as a high-powered outdoor light. I will find a use for it, as I said above, but it will not likely be a light I will regularly use unless something happens to all my other ones and this is all I have left. It's a keeper for the price, but there are many others I would rather recommend, including others by Klarus.

After reading other reviews of this light, I have to say that " EXsailor from Salem" hit the nail on the head with his review. This is a fantastic light for the sale price of 25.00 however had I paid full price for it I would have returned it. The killer is the switch and the memory function. Needs to remember last mode used, not automatically go to brightest setting. Light output is good for this small a light. The switch may be the reason this light is discontinued. I wish the maker would offer a replacement tail cap switch for this light and address the clumsy operation of this switch.

The light seems to be everything they said. Awesome sale price. I ordered 2. One for me and another one for my partner. We are both LE officer's and were looking for a good deal on a quality led light for back up and off duty carry. So far we are both impressed.

This is a super light for the price. When I saw the special on this light I had to order it. I really didn't need another light but for the price I was hooked. Quality construction. Super bright output. Really lights up the night. I showed it to a few guys at work and they all wanted one. The switch takes a little getting used to but once you get the hang of it, it's OK. You can never have too many lights and this is a great one to have at a super price.

Battery Junction had a sale on this light at a blow out price. Always a Fenix or O-light guy. This light expands my options to 3. This Klarus (XTQ1) might beat both.... .....! 18350 size

I ordered this light to see how the "click-less" switch worked along with the remote option. Everything worked to spec but the light is not practical for my use. Holding the pressure-sensitive tail cap switch for 2 seconds to turn the light on or off seems "like a long and awkward time" when the light is wanted for a "quick grab." Also, with no memory of last use, the full 800 lumen level always comes on first then you can step-it-down to the two lower levels. The three light levels seem too few; many lights have five, and I miss the "moonlight" or ultra-low level. I have yet to figure out the purpose of the rotating ring above the tail cap where a lanyard could be attached, but NBD. The light seems rugged while a "bit clunky" to hold.

Very powerful and simple to use

Handles well, easy to use, very bright light

Nice light with good features. The switch is neat as much as it is a pain. Yes it is silent and yes you have to press and hold for a sec for on and off. If you really need a silent switch than the delay of pressing the switch for a second may not matter to you. Likely that most will not find this delay desirable. However, for the sale price it was well worth the Klarus name. I just hope this trick switch lasts a long time and can take abuse.

I just bought this flashlight a couple weeks ago and I pretty impressed with how bright and how quite it is.This is a yard lighting up beast! This is the first non Fenix flashlight I've owned,not to bad so far. I bought another one for my girlfriends bugoutbag.Dont forget to buy a box of the of the Titanium cr123 batteries to go with it.

Klarus kinda' blew it on this one. The silent switch creates some weird compromises. The momentary-on function only lasts for 1.5 seconds, then it automatically turns on like a full-click on other lights. This alone sort of negates any "stealth" aspect of the light. Plus, to get the light off, it requires a release and another 1.5 second press on the switch. WTF? The tactical ring was also obviously an afterthought. It had some cheap felt material on the inside of the ring to make it fit the barrel more tightly, but this made it nearly impossible to get it over the o-ring without dislodging it from its groove. When I removed the felt, the ring rattled around on the barrel and became useless. Had I paid full price for this torch, I'd have been pissed. No wonder BJ sold it at fire sale price. Live and learn.

Snatched this up when it popped up on BJ for $25 or so. After using it a bit, I would be returning it had I paid full price. The "quiet" switch is unique and useful for someone for whom even a small click sound could be an issue, but the tradeoffs I've observed make it harder than necessary to operate for the less sound-adverse user. First, the momentary-on function only lets you use it for a couple of seconds, then the light stays on like you've gone a full "click" on other lights. In other words, if your definition of "momentary" lasts more than 2 seconds, the light stays on and requires another separate 2 second push to go off. Really limits the stealth and effectiveness of a momentary-on feature. Second, the overall tactile feel of the switch is really muted, I suppose by the emphasis on silent operation. Cycling through the modes takes some concentration, and is not nearly as easy as my other tactical lights. On the positive side, the construction is robust and the beam is nicely dispersed. This one will end up as an extra utility light around the house, and not see rotation as a carry torch in my bags or vehicles. Kinda' disappointed in Klarus on this one. Looks like they went for product differentiation over real utility.
