Review: Happy with my order - As someone new to CO₂ laser technology, I initially found the setup process quite challenging. My primary goal was to cut acrylic, but I quickly realized I had a lot to learn. Fortunately, OMTech's customer service was exceptional—they provided clear answers to my questions and ensured I felt supported throughout the process. One standout moment was the video consultation with a technician, who patiently guided me through the alignment procedure. That hands-on walkthrough completely clarified what had seemed so confusing at first, and I was able to properly align the laser with confidence. Having transitioned from a diode laser to a CO₂ system, I couldn’t be happier with the upgrade. The machine performs beautifully, and I’m excited to explore its full potential as I continue growing in this craft.
Review: I LOVE OMTECH - 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.

### ⭐⭐⭐⭐ good quality but...
*by J***O on January 29, 2023*

I did a lot of research prior to buying this unit, and I don't regret, the unit have lots of upgrades already installed, like limit switch, door safety, and many more.... some parts are not the highest quality but for the price it is a good start, and will give you the opportunity to perform more upgrades. the biggest advantage is that the unit have a good warranty, and believe me they will give you a high level support. one week after using the unit, the power supply stop working, (I was 2 cents close to return the entire unit, but they quickly contact me, and send me a new power supply), here is why I don't give it 5 stars, the unit requires alignment, like any other laser or 3d printer on the market, but the laser lens/mirror holders on the unit are super difficult to align, (they are super cheap), but with some patience, I was able to squeeze a few months and use them before buying a new set). (I haven't installed the new set, so my current machine is working ok). things to consider, laser is powerful, you can cut lots of stuff, but you will need some type of air assist, (that should be your first upgrade). if they add that from factory, this machine will be perfect. maybe after one more year, I'll buy/test the next size up, 50 or 60W, and the main reason is the bed size, and stronger rail system. this is not a sponsor review, I am happy with omtech quality.
