Excellent construction and if I'm not mistaken, it's not made in China, although I'm not 100% sure.
Very nice quality material, it supports perfectly (I bought many, 1 came out crooked but nothing tragic), it greatly increases the storage space that would otherwise remain unused.
I would like there to be an option with greater depth. As for the length, it comes in a wide variety. I have bought a total of 6 and have thus utilized even the smallest space in my cabinets.
