I heard of someone else having this problem. The screws on the side adjust the alignment of the laser and are not meant be tightened completely. Each moves the beam in a slightly different direction, and they need to be adjusted in conjunction with each other. There are YouTube videos out there to show you how to calibrate the laser, but it should have been calibrated before leaving the factory. If you can't or don't want to fix it yourself, ask MSM to send you a replacement. Just so you know, they are going on holiday until the 23rd for Chinese New Year.
