KBParadise V60 Mini Gateron Mechanical Keyboard

I joined this drop in December '15 and got the keyboard the next month. I swapped out the keycaps and keyboard case and it is easily my favorite looking keyboard. I have several keyboards that I rotate through and while I really like the form factor of this keyboard the lack of numberpad and cursor keys means it took a while to put significant mileage on this one. Unfortunately many of the keys are intermittently unresponsive or register double inputs. I would very much like to use this keyboard regularly but it is virtually impossible. Any help or suggestions would be welcome.
