A quick visit to the nearest Post Office was enough. The broken and hollow one weighs 7g less than the replacement. That is a more than 10% difference between two parts supposed to have the same dimensions, made of the same material and part of the same high end product.
A simple checkweigher would have detected such gross discrepancy, rejected the defective part (for an inspection, perhaps?) and prevented the accident. At this point I would prefer to believe that the manufacturer has an ineffective quality control / assurance in place (if it does), rather than it is deliberately placing defective products on the market. How many other "time bombs" are out there??
