GMMK Pro reviews are out. Notable since I suspect this keyboard is going to be a gateway for a lot of people getting into the more autistic aspects of keyboards. Reddit post with a summary and links here:

I ordered one - I was finding even with a TKL my mouse hand regularly hits my keyboard when I'm playing shooters online and my cm/360 isn't even that large at ~28cm. I can only imagine how bad this would be for CS people with their massive 40cm+ 360s. 65%s and under give up too much functionality.
Looks like overall the result is is 'A few hiccups but still good value for money'. Bit disappointed the typing is a little stiff since I like light keys with a lot of bump but I'm sure it won't be too bad.
