East’s to set up but looks hard taking bits off the laser but well worth it.

Noticed the difference straight away, the cuts are a lot more cleaner as in less burn on the edges. The set up was quite easy, there are plenty of videos out there you can follow, and the included instructions are clear. Very pleased with this purchase.

Have added the airflow to my machine, easy to do and it has really made a difference to finish of my projects really pleased
Good service and delivery fro xtool UK.

I ordered the Air Assist for my M1 and found it to be extremely well packaged and quality of the equipment is excellent. I thought the price was expensive, but as the nozzle and connections couldn't be purchased from a 3rd party (that I know of), the buying the air pump from Amazon wasn't an option. That said, you get 2 nozzles and 2 spare lenses. Setting it up was relatively easy, especially after watching some Youtube videos as well as using the intstructions, but struggled with getting the hose to sit correctly without blocking the camera, scraping the laser box lid or jamming behind the Y axis on return to home. However, you need an air assist when cutting, so bit of perseverance goes along way. However, improvements I would ask Makeblock to make would be:
1. Make the hose less rigid
2. Make the air pressure adjustable, as some materials require air assist, just not full force.
3. Provide a cover plate to replace the one removed to fit the nozzle.
All in all a good purchase.
