*** Updated Review After a Couple Days ***
Well, my review has gone from 2 stars to 4. Basically, the wifi app is garbage, doesn't connect, doesn't work, etc. BUT, if you just hook this thing up via USB, which is how it's really supposed to be used, I think, it is a REALLY cool machine. I was amazed at my ability to relatively quickly figure out how to do things in LightBurn with this machine. I have a slew of different scraps (as I do woodworking) and I had an excellent time once I got this machine up and running.
I will say I have had some connection difficulties and freezing issues, but they were almost exclusively related to some console commands the support staff were giving me to try and get the wifi working. Given that the app looks sort of strange anyway, and LightBurn is very nice, I think I'll just pay for that and stick with the USB. I actually had such nice results that I went out and purchased a laptop to use with this machine to really get going.
I am very enthused now and super pleased that I managed to get the thing working. It would be five stars for the value and experience if that Wifi app just didn't exist. They should have left that out completely until it was really working. Or maybe worked out some kind of USB module for it or something.
Anyway, I would recommend this laser engraver / cutter if you are relatively tech savvy and don't mind putting things together. The build quality is really good. The laser is more powerful than I would have thought. I'd recommend buying a honeycomb bed to work on as well as air assist. The price of the LM3 is low enough (comparatively) that these extra accessories will be worth it and make this device even more functional.

I cannot for the life of me get this thing working. I had some issues assembling it. They were my own fault, and I got them straightened out, but the tiny instruction booklet is written really strangely (I can't imagine why they didn't hire someone to translate this thing properly or just proof-read it). Once I got it all assembled and plugged in, I tried connecting it to the Laser Explorer app on my phone. I've been working on this for a couple hours with absolutely no success. I have no idea what's wrong. I cannot find any help online. At this point, it's looking like I'll have to purchase a separate computer to use this machine as it's not anywhere that's accessible for my current computer. Given that it's sold as having wifi, there is a developed Apple approved app for it, I just figured it would work. That I could, at the very least run a simple test of a shape or SOMETHING after assembling it. Nope. It will not connect at all. I have a bunch of 2.4 Ghz devices connected to my network, so that wouldn't seem like it was the issue and there is no other advice or troubleshooting available. Pretty disappointed at the moment and I'm feeling like I wasted 600 bucks on something that is not for beginners and doesn't function. I'm also disappointed in the reviews for not pointing out the true weirdness of the instructions and language. Maybe all budget laser manufacturers are like this… all I saw was how good a value it was for the money. It's not if it won't work, though.
