Review: New air assist for Monport 40W - Works well on my Monport 40W laser using the original lens. Was easy to install and looks much better than the original. In the next version, I would put a line on the outside indicated the position of the lens.
Review: Far better than the stock K40 head - Well made, no random chips in threads, burrs on holes, etc. Ignore silly comments about having to enlarge the mounting hole, that's user error. The head has 3 threaded parts, be sure you unscrew them all so you understand how to install. Also note it needs an 18mm lens, or 15mm with the included spacer. The standard lens in the K40's is 12mm, too small for the head, and they're usually low quality. So, you'll want to get a new lens along with this. My only minor complaint is that the screw to hold the nozzle on is a bit lame, small screwdriver needed. A thumbscrew would have been more convenient. But, that's a trivial fix.
