Great product to start with. Then the lid locked itself down while the box was in the microwave at work. No amount of gentle persuasion would prise it open. Then all of a sudden I got it open, only to find that one of the small plastic lugs, that are the hinge for the lid, had sheared off. Went to the manufacturers site to see if I could buy a replacement lid, but that is one of two pieces you can't buy replacements for. If you don't believe me go look at the Black + Blum Box Appetit box on this site, where 7 people cite the same problem.
The devil is in the detail Black and Blum and a product is only as good as its weakest link. I found this one's.
