## Description

desertcart.com : Votatu M4L-B Blue Laser Sight Compatible with M-Lok Rail Surface, Ultra Low-Profile Tactical Rifle Compact Blue Dot Laser Beam with Strobe Function Magnetic Rechargeable : Sports & Outdoors

Review: Very Disappointing (but happy now) - 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 desertcart 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 desertcart 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.
Review: This little laser is great!! - 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.
