Poor support and machine
I bought an Acmer GE1 from their official shop during pre-sale, and haven't been able to make it work at all with my Mac. The support people were very kind but no resolution and no follow up. Everything that was sent to me seemed to be spat out of an AI that did not have up to date training material about a Mac. They then reached out and asked for a video of the issue on 25 September. Despite me following up, I've not heard back from anyone. I managed to test the laser with someone else's windows computer and although it works, the software is poor (it doesn't work with Acmer Studio, it uses something called GE Lab) and even Lightburn (which they claim is supported) cannot see both lasers (it recognizes it as a fiber laser, somehow). I just wanted a portable laser at a reasonable price, but I guess you get what you pay for.
