The monitoring is a complete failure. It doesn't show consumption in watts, just some bars in amperes that you have to calculate. Even the cost cannot be changed, it is calculated at 20 cents/kWh and again you have to calculate the difference. It mentions that it can accept up to 16A BUT it doesn't mention that it measures up to 1.3A, which is misleading. The screen is simply terrible, it functions as a button and it seems like it doesn't display the month. Fortunately, I got it for €7.50 on Black Friday, as much as I would have paid for a simple power strip since it's not worth more than that.
