Worthless batteries! End up spending $12 for replacements. Wish customer support is worthless - keep sending “Did we solve your problem?” without doing anything.

Simple enough. Easy to mount and easy to adjust laser up and down. Comes with 2 packaged Allen wrenches for installation and sighting. I haven’t fired the weapon to see if laser drifts out of alignment. Eitherway, Red Locktight would remedy that. Also, the laser mount would fit a .45 or larger caliber weapon better. See video. After using it the the battery cover would not come open. The slot became stripped. It had some how became cross threaded and or seemed to have glue on the threads. In any case, I finally got the battery cover off, but not before getting mangled up to replace batteries. They only last about 90 min. The laser alignment does drift and will need Locktight.
