Laserbeak Laser Sight with USB-C Rechargeable Battery | Compatible with M-LOK | Green Laser | Flat Dark Earth

It works good but, battery is getting low without using very soo. You'll walk to use and ops it's dead

It seems I'm not the only one to mention this, but these do not hold their charge. These charge pretty quickly but if you leave them uncharged for around 3 days, then they're dead. I regret buying 4 of these in misplaced enthusiasm. Also the grip and mlok mounting is awkward. It's too smooth for a good grip, and it doesn't play well with other accessories on the rails. The nice pro is that the laser itself is bright

Product is well made and sturdy with a high quality laser beam that is broght and maintained a zero. A problem I've noted with this item is that the battery life doesn't hold over long periods (a couple weeks). Without constant upkeep charging the laser battery depletes even without use.

I had high hopes for this laser to use on one of my guns since it is VERY bright and the beam dot crisp at all distances. However, the charge on the device won't last more than about TWO (2) WEEKS at the MOST sitting on a shelf. That is unacceptable in the extreme IMHO. I've had the unit for a while now and have tried charging it multiple times hoping the battery would "Burn In" and give me some longevity but nothing has worked. Now I hope it isn't too late to return it for a refund. I CANNOT RECOMMEND THIS LASER DEVICE AT THIS TIME. Perhaps I got a Bad unit, I don't know but I sure don't have ANY faith in it at this point. Perhaps someone else can comment and advise that their unit has worked for a MUCH longer time without the battery dying in short order. That doesn't inspire confidence at all.

Decent battery life, very bright and holds zero perfectly.

Arrived with a completely dead battery. Lithium batteries don't like to be completely dead, it can cause long term damage and capacity reduction. That's why most things that use them arrive around half charged. Most integrated charging systems have some kind of low voltage protection to protect the cells. This may, I dont know but depending on its voltage cutoff and then how long these sit on shelves somewhere it could have something to do with the other complaints I've read about short standby times. This thing feels kinda beefy to have a small battery, not sure if it lists the battery capacity anywhere or not but it feels substantial. Havent mounted or zeroed it yet so I can't comment as to whether it holds or not. But it does feel well made for whatever thats worth. However, I would use it on more of a fun gun than anything you need to depend on. But I tend to say that about everything so take it as you will.

I had the option to purchase either a blue or a green laser. I chose the green in flat dark earth. The laser charged pretty quick, though I did not time it. The interface for the charging port is covered by a thin rubber sheet that requires the rubber plug molded into the flap to engage the USB-C port to hold it in place. It takes a little fiddling to get it right, and you will know when you do. Until then, the flap remains loose and unclosed. When it is properly seated, I have confidence it will keep moisture out. As another user noted, the power button is located on the laser opposite the charging port. There is no remote trigger operated switch, so to use it tactically, you will need to switch it on with your free hand. There are 2 small allen key adjustable screws at the front of the laser to facilitate elevation and windage, though the instructions don't give any indication as to what a 1/4 turn will achieve in downrange adjustment. I took the bare laser outside and tested it on a sunny afternoon to gauge visibility. Looking into the sun, I was able to clearly see the green dot at a distance of about 75 feet. I turned to the north and shone it on the neighbor's yellow-brick garage about 120 feet away with the sun shining on the brick and was able to see the green dot. It was a little harder to see, but if you walked the dot up on closer surfaces, you could make it out once it landed on target. If the laser was attached to a longarm, it would aid in dot acquisition. For an M-LOK laser that doesn't cost a ton of money, this one works well.

The battery will not keep a charge. It is completely dead in 21 days or less, (with no use). Not a good thing for a home defense situation. Complete waste of money.
