I have a commercial 90 watt Co2 laser. It is manufactured in China, and rewired in the USA by Aeon Laser USA, to meet local standards. It is a lot faster than hobby lasers, and deep enough to engrave objects approximately 5 7/8" inches deep. This depth allows me to engrave cylindrical objects, such as tumblers and ammunition cans. It has a spacious working area of 23 5/8″ x 35 1/2″, in addition to an access door that allows me to cut, and engrave items larger than the working area. My Mira 9 meets all my needshttps://aeonlaser.us/contact?ref=Thelaseroutpost
