The idea is great, but the execution is lacking.  The quality of the plastic is pretty low end.  One of the little brackets was broken on arrival, but it is just not worth sending them back.  I plan to use them almost exclusively for storing deviled eggs in my own fridge, so I think they will be adequate for that purpose.  I would not recommend them if you plan to use them for frequent travel/transport.  I don't think that they would hold up well to that.  I think that the quality is probably in line with the low price point.  I may upgrade to a higher-end product when this one reaches the end of its useful life.  You get what you pay for!
