At first I was really impressed and excited with this Laser sight system. I was sleek, low profile, fit seamlessly in to my M-LOK handguard, easy to charge, easy to sight in, and very bright blue dot on target. I fully charged the item as recommended in the instructions, and installed it on my S2000 KelTec 9mm. I took it to the range, and after only 20minutes of use, it just turned off and would not turn back on. I assumed that it was just in need of recharging, so I took it home and left it on charge5r for two hours. Green indicator light confirmed full charge, but the unit would not turn back on. I tried to resolve the issue directly with the manufacturer "Votatu" which claims a one year warranty, but turns out you cannot be contact them directly, except thru email option. The instruction manual only lists an email contact, a facebook page, and a blank website page (because it not set up yet)... No phone number provided to resolve, so I regrettably returned it back to Amazon as defective. I really liked this product as there is nothing on the market that fits my rifle as perfectly as the M4L-B. I am tempted to just reorder a new one, as the Amazon reviews are overwhelmingly positive, but when a vendor cannot be contacted and is not available to resolve warranty issues, then I cannot trust them to provide solutions for me. ***UPDATE!!! ... I am changing my rating from 1 to 5, due to the incredible customer service of this vendor (VOTATU). They proactively read my "disappointing" review above, and reached out to me directly (without prompting) and immediately sent me a replacement unit. This is a vendor that stands behind their product, and takes care of their customers. I was very impressed with the product initially and now I am very impressed with VOTATU, and I will definitely choose them first whenever I have a choice. It's really refreshing to deal with a vendor that treats their customer right and I am happy to give this laser system a second chance.

This blue laser is extremely bright and holds zero well. Compact and lightweight with easy controls. Great for home defense or target shooting. Installation took just a few minutes.

I was excited when this Lazer came in the mail the other day. This little Lazer packs a big punch for its size! The sleek smooth compact size really plays a great part for the grip and feel for this product. I love where the button is placed for this Lazer too it’s very comfortable with my grip.. it can be mount anywhere on the M-Lok hand guard this is a huge plus.. it’s very easy to change your wind and elevation dials. Included in the box was the hex key for this.. I was very impressed by this product from Votatu this is my first product from them and I will definitely get more. The costumer service was great and the package got here fast. I was able to take this out to try and it was very impressive. It was simple to adjust and zero in best part it’s stuck there all day! This is a great laser the blue light is very bright and easy to see. I didn’t have a need for the strobe function but it was still easy to use. Lastly this is rechargeable so no more worrying about batteries. I highly recommend this product for those in the market for a new laser.

Really slim laser that appeals to the eye as far as adding gun attachments. Great feel when you have to hold your barrel to aim. Finger groove on it makes it easy for a finger to rest on it. Really bright also! I have not taken it out to the range yet but 10/10 on the look,feel and brightness.

bought this planning of getting another if it worked out and unfortunately I was a little rough on it i put it on my ar and well it didn't last long it still turned on but it became a strobe lazer now for 22lr and airsoft it would be just fine it works well fits well, looks good, and the button and adjustment system works well.

I have not taken this out and field tested this for holding zero etc etc. This is very compact and streamline I noticed a bunch of ads for lights and lasers try not to show how large or small the product is so I'm usually finicky about buying something I haven't seen in person but am pleasantly surprised she pleased with the size of this laser. There is a slight delay from when you click the button and when the laser is on also the button is nice that it is very low profile but I think it could protrude a little more it is kinda awkward on my set up. If there was a remote option that would be much nicer. The price is good the build is good so far. I really like the push to these magnetic chargers you don't have to remove the laser just plug the charger in the wall let the magnetic end connect to the charge port when the LED changes from red to blue your good to go. The blue laser is brilliant and definitely will work for fast action and quick acquisition.

I got this laser to see if it was easier to catch with the eye and track on movement so low light and the dark works great

I fully charged this laser sight. I did not touch it for a week and it was dead. I charged it again, overnight making sure it was fully charged and again in one week of not touching it was dead. This is useless on a firearm.
