Everyone is entitled to an opinion. Why should a consumer pay for the use of a faulty product? We were mislead into thinking the ball met regulations before we put holes in it.
As for a ball that cracks, we now have many variables in play. Did the ball sit overnight in freezing temps after drilling? How about where was the pin in relation to the drilled holes? Did the ball bake for too long at a very high temp? Did the driller use bad drill bits? Did the driller drill too fast, building heat around the cover and cause the cover to be brittle? Was it a manufacturing defect?
We don't know as it could be any of those issues...or anything else (simple wear and tear from being throw down a wood lane for 60 feet, impacting pins that weight 3 + pounds each, hitting a machine, and being rolled back down the lane to do it all again?
However in this case, the ball was out of spec before it was in the consumer's hands. Not caused by use, or a bad PSO, or bad manufacturing, or lots of use....this was 100% Motiv's fault on manufacturing a product out of spec.
