Package List
This was a great upgrade from the 10w I had been using. I'm able to get many jobs done quicker with beautiful crisp lines. Also cuts very nice.
Three years ago I bought the 10-watt Laser Master 3. It did its job very well, but over time the thicknesses to be cut increased. I was planning on getting the 40W, but I was right to save a little and get the 20W. The pros are definitely the cutting power, the cons are the noise, but above all, I don't see the need to power the fan even when it's not running. I mean, you just power the Ortur, which activates the fan. What for cooling? Otherwise, fantastic.
Easy to install, and fast engraving and cutting
