The lase machine works better than I expected and is quite useful for the tasks I bought it for. The installation and setup were very quick and intuitive. I like that I can connect to the unit wirelessly from a PC or laptop.
The manufacturer does not put much stress on it, but the unit is equipped with a built-in exhaust fan. I was impressed with its power and how it works. When the machine is on, the fan spins at a relatively low RPM, apparently just providing cooling for the electronics. But when you cut, it AUTOMATICALLY turns to the a high RMP and then falls back to the low shortly after the job is complete. May seem like a little thing, but very clever and saves both the power and sanity - the fan is very noisy when on full throttle.
The other thing I really wanted to highlight is the camera preview. This is much more than just a convenience and is a real time saver, helping avoid the frustration typically associated with aligning graphics to cut relatively to the work piece.
I have successfully used it for precision cutting of plastic films and sheet blanks to different sizes and shapes. I have not used it for engravings though.
For my purpose, the tool seems to be ideal. The software is very simple, rather minimalistic, but works for my purpose.
Overall, very satisfied with the product, hoping that it will last.
