Query: Much wasted money on these, they invariably crack for no reason

As many other users here, I've purchased a number of these canisters and they all seem to eventually get cracks. I've tried to treat them with kid gloves, not putting them in the dishwasher, being careful not to overseal them, etc. Doesn't matter, some crack even after just a few uses. I have one tall one that still seems to be okay, and the square marinator, but these round canisters are just very unreliable. With all the complaints, I'm surprised there hasn't been a class action suit against the company for knowingly continuing to sell such defective products! I now generally use medium and large mason jars and seal them with the handheld unit and jar sealers. This works so much better, but has limited space of course, even with larger jars. It's a shame Tilia can't get their act together and make canisters that will last.
