I had seen complaints about the lasers not being aligned, and I never experienced that issue. To test alignment, I placed each laser on the desk and rotated them around, holding position using a square I had clamped to the desk. They all maintained alignment, measured by the laser holding position on the ceiling. The only issue I noted was with my Holosun HE507C GR optic. While the lasers were visible through my 407C and Osight SE, it was very faint while looking through the 507C. I am not sure if there is an optic coating used on the 507C vs the others, but I had to turn down the brightness on the 507C in order to see the laser. Overall, I highly recommend this kit for anyone looking to initially sight in their pistol red dots.

But- batterys are cheap (and maybe just the battereries included with the unit are just old/weak?) ,commonly available . This device is a lot cheaper (ammo costs about 40 cents a shot nowadays) , and much faster than wasting range time on this extremly important task. Even if the battery life issue is not fixable with fresh battereries -I'd still rate these units very highly-they are so quick to use that you can just remove the batereries after the five min. or so to adjust sights. AND-works fine in .38 special/357 revolvers -leave the cylinder open -the bore sight will hang out the back -but the 9mm will fit into the barell and allow you to adjust sights on revolvers in those calibers. Final point: Boresighting fixed sights can be sobering -but better you know than you guess they got it right at the factory.
