I have been using the Chosera's a lot over the last 12 Months or so, and have not seen any signs of that as of yet. I soak mine for 15 mins or so before use And keep them submerged for a whole evening a couple times a week. After use I let them slowly dry in a towel. I think it was holli4pirating that reported some cracks in his 1K a while back, but other than that, I haven't heard much about Chosera faults on here. There are quite a few of us who use them round here, so I would think we'd have heard more about this if they were all that easy to break
