The first unit that I received had no packaging, and the lid had to be pried open. Once we got the lid off, we found that it didn't really fit well with the pan itself. It would get stuck whenever you tried to slide it shut.
I requested for a replacement, and the 2nd one that I received was wrapped in proper retail packaging, and the lid slid on and off without any fuss.
The product itself worked as expected and was generally of decent quality.... assuming you get a good one.
