I researched the various machines on the market at this time (April 2025) and decided on the ComMarker B4 50W as being the best value, and bought it from Amazon as being the least commercial risk. It arrived a week early, in perfect condition, and has worked brilliantly. Its taking me a little time to find the best settings as I am also learning Lightburn at the same time - so a steep leaning curve! EzCad was an issue as it said it was a Demo version, even though it was registered to me.... however, I was never going to use it.

This is powerful. Best thing i have ever bought. Easy to use, accurate and well built. Expensive but definately worth it.

Misleading It says in the description that this unit comes with a rotary drive. I did not get a rotary drive.

Customer support is excellent in this company, I had some minor shipping damage and the rapid, proactive support was excellent. Have purchased a larger lense and z axis piece and that too was perfectly executed.

Customer service was good leading up to my purchase, and the machine arrived after about two weeks. It’s a lot bigger than I expected. The instructions were okay, but since they were translated to English they weren’t always easy to follow. After some trial and error I managed to download the software and get it working. When it worked, the engraving quality and speed were very good – I got some tags engraved cleanly. However, I found the machine quite difficult to use. Even with the blue light outline it was hard to line items up, especially in a large workspace. Because it’s an open machine with no enclosure, I had to wear the glasses constantly, which was inconvenient. What really held me back was the software (EZCad). I struggled to find clear instructions, especially for tasks like engraving the inside of a ring. The options shown in YouTube tutorials weren’t available in my version, and even when I tried updating, it wasn’t straightforward. In the end, it felt too complicated for me as someone new to laser engraving. I ended up returning the machine and choosing an alternative model that better suited my needs (engraving jewellery and other materials smaller workspace and enclosure ) For someone with more experience, this could be a very capable machine. For beginners, I’d say be prepared for a steep learning curve. Value-wise, the machine is priced well.
