For K7, Murphy is an optimist!

It IS a Chinese POS, but if you understand what you're doing, may not be a bad deal. I bought this one on fleabay years ago, knowing it was a cheap Chinese POS. However, it has done its job. Tight seal, looks okay. I think I paid 50 bucks with shipping. At about the same time, we were renovating the kitchen, and I bought an extra cabinet to turn into a humi. I kept the cheapy to use as dry box.
