When I built my cp, I ordered a button wrench along with the other controls. Unfortunately they sent me the wrong size (wrench) so I ended up tightening the nuts as best I could with pliers. Later, I did get the correct size wrench but by then the buttons (and LEDs) were all wired up - and they seemed tight.

That was, until my son and his friend played Track & Field for a few hours.

I guess the constant pounding just vibrated the nuts loose. That is one abusive game!
And to top it all off, they broke all my records!
