I bought this for my wife and she got it on Christmas day. I plugged it in and it got hot. it does not work. The screen displays 350c and flashes. What's frustrating is not knowing what that blinking means. The manual has a typically poor English translation. Troubleshooting isn't talked about anywhere, and there's no way to contact the manufacturer if you have any questions. I assume the block is broken. The Revain return window has closed and cannot be returned. I just hate spending money.
