I used it once without any problems, but it stopped working the second time. I contacted the seller, but they couldn't figure out the reason, and sending it in for repair seemed like a hassle, so I'm selling it as junk. The exterior is relatively clean as I haven't used it much, but the inner pot has some scorching on the bottom from being used a few times. Please check the photos. This is a junk item, so please be aware of this before purchasing.
