Not sure on the guarantee but I contacted the link above. It will be $41/shipped to get the top latch replaced.
I had a former team member ask to use my break cue. I look over, and he's yanking on the top of the case like a wild man. I say "Hold up!" from across the room. The bar goes quiet. I walk over and look at him, tilt my head sideways and say "Try this, Einstien..." and untwist the latch and flip the case open.
Needless to say, he loosened where the latch attaches and I babied it for the last year but one side finally gave.
Can't ask any company to cover for someone else's stupidity...mine, for lending my stuff to a bonehead.
Believe me, if I knew where the guy is today, he would be handing me $41 to cover for his mistake.
You can't fix stupid...
