Hi there,
It was perfectly fine after we put it together… Just that left and down buttons couldn’t be pressed after putting on the covers…so we wanted to straighten the soldered buttons a little…
While desolder the slightly slanted “left” and “down” buttons, I destroyed the motherboard … Ah… . So sad… this was my son’s birthday present… Any chance that I can buy a whole new set at a cheaper price… Devastated…
