Two very very important takeaways here for every pin owner :

1) NEVER set the game down on concrete or tile, and NEVER lean it up against concrete or cinder block.

ALWAYS set it on carpet or some thing soft (like a towel) and lean up against wood/drywall only (or use another towel if wall is concrete/cinder block

2) NEVER knock the edges ... always handle the glass by the edges, moving it slowly and carefully.

It's possible to break it ON a game merely by tapping the edge on the metal glass channel covers, or touching the bottom edge with the hand protector (what we call the lockdown bar).

BOOM!
