In summary my experience starting with a GMMK Pro was very mixed, it had a lot of issues for the price point but i'm using it as my gaming keyboard now and am happy with it.
I also got some other boards already that enjoy so far.
I'm looking forward to maybe at some time contributing something to the community as well. Currently i'm dabbling a bit in stabilizer wire mods with spay paints. Ill let you know if i find something usefull.
kind regards, so_below
