Review: Super fast - Great product - after 2 hours of not working realized that we had the water hoses on backwards. Then boom it worked amazingly.
Review: Updated: New replacement tube works great - Update: after contacting the seller, they promptly sent us a replacement tube, which runs great. Easy installation. Healthy and stable beam. Clean cuts. Happy kids. I hope this tube will have long lifetime ------------------- Purchased the machine in July, and have been using sporadically, once a week or so, for short low-intensity jobs (10% of laser power). Worked great when it was working. However, even with adequate cooling (the coolant temp has always been within the 18-20C range), the laser beam switched to the doughnut-shaped profile in November, i.e. useless for any kind of job due to the inability to focus the beam properly, and now the tube has to be replaced.

### ⭐⭐⭐⭐ 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.
