First off, the laser was barely visible in the newly-renovated firing lanes, so sighting it in wasn't even an option.
Secondly, with just 25 or so rds. down range I noticed the battery cover on the laser was loose and in need of tightening. Same thing happened after the next 25 rds. And the next 25. And so on...
By the time I had exhausted my allotted 150 rds., not only was the battery cover loose again but the entire rear sight had slid over to the right a good 3/16 of an inch. (Meaning the laser's center securing screw was also not holding up to the recoil of the gun).

After repositioning the rear sight to it's proper location and securing it as tightly as I could, (without snapping the miniscule allen wrench in two), I noticed that the laser itself was now a little bit off to the left from where I had originally calibrated it.

Anyone have a better experience with this product than me?
Anyone have any tips for preventing these issues from occuring?
