Ill post a review in a few days. Its probably not going to be up to par with the veteran laser doods here, as i am a newbie to the hobby
The focus ring threads on to the cylinder, for lack of a better term. so when i went to focus the laser, it would just move on the threads and not actually focus the laser. So what i had to do was pull the threaded cylinder out and manually tighten the ring to it, so i could focus it. .
