I wasn't sure what I needed when I purchased the D1 but began to realise that, if I wasn't going to smoke the house out or burn my final product, then this Air Assist was definitely what I needed. I purchased the item and it arrived very well packaged. It was easy to install because with all the products on this site, they come with very clear, easy to follow instructions. Now Im no tech wizard nor builder but I found it very easy to install and navigate around when it came to how high to have the setting etc. So if you are just starting out, get this air assist because it will save you alot of failed products and your work area is so much less smokey!

Quality built as you would expect, good air flow which certainly does help in reducing burn marks.
Disappointed in that on a machine of this quality and price it does not have variable airflow

I initially tested the D1 Pro 20W without this as it was still boxed and could see the issues this had on the output results. When i put this on it changed everything because it added to the quality of the product's output results. No more smoky, burnt residues etc. Very worth while add on to the laser engraver.
