I have bought several items over the past year one being his nozzles the three piece set. They are far superior than the nozzle that came with my Monport 80w Co2 laser. They came with a reverse laser alignment tool, that cut my alignment time in half. I have had my laser for one year now and added a red dot assist that screws on to the end of any Yongli A/H 80-150+ tube. During alignment of the red dot assist the red dot was not a dot at all but many dots. Spoke to Lou (he must wonder what now when I call) and he recommended replacing the mirrors. Wow what a difference they made. In picture below can see just how bad the original mirror was (one on left if not sure lol) So now my red dot comes out tip and is so much more precise the the red dot that hangs off nozzle and this has elevated my work.

Shout out to Lou for helping me figure out what I needed via chat. It was so simple to order. I highly recommend this shop!
The mirrors helped me fix my FSL Muse Core.
New mirror on the left replaced one on the right!

Spoke with Lou, many many times as I am new to the laser rage...
he always and quickly responded to all my emails, even those that I should have probably done some due diligence :).

The kit was great, need it to cut thick Acrylic so tried the 2.5 " lens and it was fantastic. I also picked up the 25mm mirrors to upgrade next as These are much better quality than the chinese supplied with the laser unit...
The lens fit great in the Monport 130W, price was to my surprise super !
For a small $$ investment I feel I have taken the Monport to the next level of achievement.
Please consider buying from these folks, I love Steve Walters videos, hope to see more as they are full of direct information that helps and explains some of the common questions we all have..
I have included a couple photos, getting the Monport setup and first cuts with the APC 2.5Lens on some 10mm acrylic...
Loving the new APC items and will not consider any place else for information and supplies...
Great job guys.... thanks to Lou especially...

I thought my stock lenses we’re good until I swapped for one of these!
I can cut faster with lower power
Also get darker engravings at a faster speed
Incredible!
10/10

Finally some laser equipment that the manufacturer has put some thought into. As a new user to C02 lasers but not cnc machinery it has taken the guess work out of lenses. I don't think most owners understand the lenses and alignments but I feel like an expert now.

I've even made a durable storage box to keep them in.

Well designed and easy to install. Good quality. The air assist adapter that popped up as something usually bought together will not fit. Same size as the stock adapter and too small for the APC. Glad it wasnt too expensive but still feel if something is going to be advertised it should fit what your buying.

Works great cut focus time and helps u see mirror movement my tube was out and mirror pedestal was out too. The reverse tool help getting parallel to gantry pretty fast after I diagnosed the pedestal was out

Work just like I designed them, also could get some Combining and Collimating lens.... Thanks Joe Engraver's Choice SST

Great lenses are the key too doing Great work . you can find cheaper lenses but remember .. (GOOD THINGS AREN"T CHEAP AND CHEAP THINGS AREN'T GOOD !! )

Works great and is easy to clean

Super easy to install, fitment was great. The lens is very easy to remote and clean. This was a great upgrade!

Lens worked perfectly

We have 2 Trotec Speedy 300s and have used these lenses with great results. They’re a fraction of the price of the oem lenses with no measurable difference in performance.

Good Price, shipped quickly, good customer service
