I actually got it to work, for a short while. It was reading negative numbers, so I switched some leads around and I think I fried it. It just holds the SDA and SCL pins low now, even after figuring out how to restart the i2c bus. They clearly stated there is no reverse polarity protection, so it is my fault.
Very good, cheap and measuring is accurate! I am satisfied!
