I bought this equipment there 1 year and 1 week. It worked very well, reliable and convenient in reading data, real source of savings (I learned that my subwoofer consumes 30 W in sleep !!). By cons, it is breaking down: whatever the device plugged into it, it indicates 0-0,5W consumption, that is to say, it no longer detects anything !!! So very disappointed in the quality of the product over time !!
