I bought a Zwilling vacuum pump and 12 small glass vacuum containers. After two months, the vacuum containers are no longer sealing properly. Some of them pop open after a few hours or a day or two in the fridge. I haven't managed to determine which ones out of the 12 are causing the problem. Trying to clean them thoroughly is very difficult. I have followed the instructions in the video on YouTube "How To Clean The Containers & Lids - Zwilling". What it doesn't tell you is how difficult it is to reassemble the lids. It is very fiddly, especially fitting the flexible seal into the inner lid, and takes about 20 minutes to reassemble each lid. If you don't take them apart to clean them thoroughly, there are lots of spaces for bacteria and mould to grow. Potentially dangerous to health. I have written to Zwilling about the sealing problem and they said I can return them under guarantee to be "evaluated". That is not really practical. What I want is a reliable product that can be easily cleaned. I may revert to using my low-tech Pyrex containers which I`ve had for 8 years.Update 20-Sep -- Thank you for your reply and generous offer to replace the lids. I have been cleaning the lids very thoroughly and that seemed to help, but this morning one lid had popped up in the fridge. I have taken a photo which I will send to your support. I would like to take up the offer of replacement lids.Update 11-Oct -- The 12 replacement lids arrived and that has resolved the problem. Thank you, Zwilling!Update 27-Jan -- I am using the vacuum storage all the time and would not want to give it up.
