100% OK. btw in POLAND use FR not EU.
I ordered from a Russian warehouse, on the fourth day I delivered a courier (Moscow). I chose the Wattmeter for a long time, and this model is the most functional of the inexpensive ones. High-quality assembled, thick plastic, no creaks and crevices. The voltmeter readings are correct. Unlike its counterparts, this model does not distort the power readings in watts (doubles) if it does not have batteries. It has a very useful function, it shows the maximum values in amperes and watts per measurement session.
