The CO2 laser has all the bells and whistles you need. Even has Safety latches, if you open a door the laser stops burning. Designed with the user in mind. Cuts as advertised and is far better than my old K40.

The OMTech K40+ (Plus is important) is not the cheapest K40 around. But this is because its packed with a bunch of features you'd otherwise have to sort for yourself if you bought one of the cheaper models: -Upgraded GRBL compatible control board so you can use Lightburn right out of the box. -Contact sensors that prevent the laser from firing when the lid or collection tray is open -Honeycomb bed. -Adjustible height lens so you can get the correct focal point without having to raise or lower the bed. -Included led light so you can see your progress -Height-adjustable feet to level the machine - Other options I've surely forgot to mention If I had to ding the machine for something, it would be the positioning of the collection drawer contact sensor. If the collection drawer is out even by a hair, the laser will refuse to fire and you may not know why. I wasted quite a bit of time trying to troubleshoot my laser not firing without any feedback that the answer was very simple, nudge the drawer in a bit. I can foresee a situation where vibration could also lead to it sliding out in the middle of a job. As long as you know about it, its not that bad of an issue.

OMG…This is my favorite from OMTech, and I own another one it’s the 60w fiber laser. There lasers are the absolute best. The quality of the work it’s does is amazing and the ease of use flawless. I love OMTech. I’m saving to get the 100w Co2 laser, won’t settle for anything less.

Love my laser. It has been great to use. I did upgrade and get a chiller because it seems to run warm even in a cold room.

It works but there are better machines for less money. I doubt that it is the power stated. Probably more like 30 watts. Very small work area. But I knew that going in. Won't know for a little while about durability and longevity. Customer service is slow to respond. If you are looking for a quality machine, I would look elsewhere.
