Good product (with good service)
My head arrived with 1 of the 4 parts that did nog have good thread on them. After sending a mail to LightObject a replacement part was shipped very fast.

Great upgrade
I didn't think it would make a difference, but I was wrong. One of the best upgrades I made so far.

Good addition.
This is by no means a "magical" answer for a cheap old DC-KIII/K40. However... I've worked production for nearly 3 years, using a 120watt Universal. This, by no means, make it's equivalent. But what it does do, for those that take the time to learn, can turn a $400 desktop laser into a producer! It DOES push smoke and flame away from the sublimation point. But you DO have to be mindful of the focal point and speed of the lasing head. Great buy for those interested in the actual production value of an inexpensive machine. The quality of the head itself?? Aces, baby.

great upgrde
Lightobject does it again, great and affordable upgrade. It makes the laser much more reliable and adding the air keeps the lens clean. I read another review about it not fitting but it fits mine fine and I'm sure I have the smaller size mounting plate. I upgraded the lens as well which is awesome. Super fast shipping as well had it in 2 days. I highly recommend lightobject for all your laser needs!!!!

Great upgrade
Got it to work now thanks to phone assist from LO customer support. Info (same as below from LO) got it working and it works great. Now 5 Stars and I'm very satisfied. Reply by LO: It has a 14mm threaded end The bracket dimension is one side with 14mm and another side is 22mm. Pictures showing the threaded part with different size in diameter.
