Good, but could be better
The quality of the product is descent and fits very well on my cheap chinese laser CNC.
The worst part is that the opening where the laser and air goes out is VERY big! (6.5mm) The air output will be very low unless you have a very big compressor, mine is 23L/min and with a narrower nozzle the air output would be perfect.
Although the big opening is good for those who dont have a good centering of the mirrors, so the laser will go out easily through this opening.
Also be careful, this laser head is prepared for 18mm lens, my laser came with 12mm lens and there is no good way to fit it inside without some modifications.
