Bests & Worsts Reviews from Amazon

I got the first one, and after I plugged into power outlet, I immediately detect there is electrical leakage. I requested to replace it. I received the second one pretty quick, thanks for the Amazon's delivery. It was working fine, and no electrical leakage. However, just after only two days, I got electric shock. I tested it with my digital multimeter, I can detect around 52 voltage just by touching the outside of pot surface. It is not always being detectable, but it happens frequently, lasts couple seconds to couple minutes, and then it looks okay. After a while, it happens again. This is unsafe product, and it shouldn't be on the market. I called the customer support, and I waited for 25 minutes to reach an representative, but she just created an case....
