Pistol Green Laser Dot Tactical Adjustable Low Profile Picatinny Rail Rechargeable Battery - $17.35 + FREE Shipping

I've purchased several different laser sights/combos/boresights etc from Amazon. Most of it is cheaply made and low quality, and it's best to always test it immediately before the return policy expires. With that said, occasionally you'll get a "keeper"; a unit that functions as advertised and holds up to normal wear and tear, and holds zero. But it's always a roll of the dice with these cheap Chinese electronics... I have several of these no name lasers/lights on my range guns. But I keep an Olight Baldr Mini on the Glock in my nighstand. It's fun to get a decent laser for $20 bucks, but I'm not gonna put that $20 laser on my primary home defense gun.
