Item feels good but once you tighten it on its rail mount, it puts pressure on the base causing it to constantly stay on burning out your battery. Will need to look at the interior to see the wiring. Out of the box, this item doesn’t work.
RMR's were sent fast and packaged well. The Red Dot Sight works as advertised, the red dot is sharp and clear. So far so good, I am quite impressed. It mounts with a snug fit, at least it did on my 9mm Glock 17 MOS. I can not say yet if the red dot holds its position on this real 9mm firearm. I will see.
