Product review (4 stars): Wash by Hand and You will LOVE them ....
I wanted to use these for awhile before making any comments.  I have had these close to a year now and they are holding up very well EXCEPT when my husband made a bit of a mistake by attempting to wash the egg container in the dishwasher.  It is now warped, the lid completely ruined.  I love being able to organize my refrigerator better just wish they were dishwasher safe. I can not complain about that because I honestly can not remember if the paperwork that came with it advised against that or not.
