Great diode laser. The price seems high, but these lasers are nothing like the cheap Chinese ones. It took a little fiddling to get out setup on my Ortur Laser Master 2, but with help from George I got it working and I couldn’t be happier. Great for engraving! Done people cut thin wood with this laser, I think if you’re looking for cutting, get an O2 laser. If you want to quickly engrave, this is definitely worth the price!
