Review: Works perfectly! - I don't know what other people are having problems with, but I couldn't be more pleased with my new laser head. I bought a new high quality mirror and an 18mm lens for my new head. After my initial adjustments it's working way better than the old crappy head & lens. My calibration is off now so I need to recalibrate my software to my machine but that's not a big deal. I haven't permanently hooked up the air pump yet because I bought the wrong size hose. Oops! I temporarily hooked it up with the too-big hose and it works amazingly! My experience: - I didn't break a lens because I didn't screw it down too tight - Nothing is coming loose because I put a tiny bit of blue Loctite on the threads - I didn't need to machine a custom part for it to blow better because I have an 800gph pump that works great - It came with an adapter ring so I could use the original crappy tiny lens if I wanted to, but why would you? - I didn't have to adjust my bed because the lens is the exact same height as the original - Some instructions would have been nice, but definitely not necessary. There's only 3 parts, 2 screws and a mirror clamp and the thing is already assembled, so all you have to do is take it apart and pay attention! There are also YouTube videos out there if you need a hint or guidance. I mean, if you're smart enough to configure, adjust and run a laser you should be smart enough to figure this out! If I needed another one I would buy this again! It's not a car so don't torque things down too tight, use a little loctite to keep things together, and get an adequate air pump. Success!
Review: Good stuff but small issue - Love it. One issue, the screw that came installed to hold the air assist portion on the head was not quite right on the end and wouldn’t screw-in tight enough to hold it in place. To fix this I ground the end of the screw down to get to the good threads and it worked perfect. Still giving it 5 stars because it is a great deal at $20 and serves its purpose well.

### ⭐⭐⭐⭐⭐ Great piece
*by C***0 on May 7, 2021*

At first I was torn about this. The lens and mirror part worked perfect. It literally took me forever to get the air assist pet to work right without bouncing the beam off the inside. I don’t know why it took me so long to figure out that I needed to put it on first and then connect the air assist line. Works perfect
