Review on TEN HIGH AC110V Engraving Cutting Machine Beading & Jewelry Making by Wendy Rodriguez

I was able to install the tube fairly easily. When readjusting the mirrors, I continued to receive two beams, as if the beam were hitting the metal frame around the mirror and splitting there. By placing a small piece of cardboard at the exit point of the laser from the tube, I verified that the lack of coherence was OUT OF THE tube! I'm returning it and am willing to try another. But heck if it wasn't disappointing to go through the tube installation process only to find there was a problem. I will update my review if the replacement works. UPDATE: The replacement tube was great! Good coherent jet with good cutting ability!
