Satisfaction

Originally, I had a 20W diode laser.
Then I decided to purchase a ComMarker MOPA 60W.
Encouraged by the easy purchase process and the usability of the IR engraver, I also bought a 5W Omni1. I haven’t tested all of its features yet, but everything I have tried so far has worked flawlessly. I can recommend these models to any DIY enthusiast.

One Laser to Do It All in 2025? The OMNI1 Might Be It

I started laser engraving back in 2021, and the progress in just a few years has been incredible. Prices have dropped, and high-end laser technology that used to be out of reach for small businesses and hobbyists is now more accessible than ever. When I first got started, you needed multiple lasers to cover different materials. But in 2025, with just one or two machines, you can handle almost anything you want to engrave. The OMNI1 UV laser is a game-changer. It covers such a wide range of materials that for many people, it could be the only laser they ever need. One of my dream capabilities was glass engraving — and this UV laser not only handles glass beautifully but also delivers stunning high-definition images that truly blew me away.

So far, great!

The laser is doing a great job so far. Doing some material testing still. My only observation is the type of power button. A up/down toggle or something that does not push in might be better. But no big issues at the moment.
