While I agree it’s great work, I don’t believe there are a lot of Chinese laser owners who are worried about the GF. You have a couple of levels of Chinese lasers - the really cheap ones (<$500 or so) and the expensive ones that are more in the line with the GF. The first group isn’t going to spend $3000 or $5000 on a laser that does what they can do now (or even some things they can’t - while also losing something like rotary engraving) for 10X the money.
The second group has the money but the GF isn’t the same standout improvement for them. The software is generally a fair amount better than the K40 types and the bed and tube power is radically higher. For the price of a GF Pro I can get a 120W with a 3x4’ bed, Z-axis adjustability and rotary engraving capability. I couldn’t do one-pass 3-D engraving but I could mimic it fairly well with a multi-pass approach. So if I already own one of those beasts, why would I be bothered by a machine that can’t handle the material sizes I would now be used to handling? The workflow benefits wouldn’t be compelling because I’d already have gotten used to them.
I don’t think you’d find many Chinese laser owners who are worried about the GF, just jealous maybe of some of what it can do.
