I think there isn't more to do here
I bought this off from CL4P-TP.
Lube the stabilizers and switches with Superlube grease and oil, switched out the F,J and numpad 5 keycaps for bumped ones for touch typing. And it's now perfect to use!
I can't record the sound with a proper microphone until vacation sadly
But even with the shitty mobile, these sounds so full and thocky!
