After my old Energiekostenmeßgerät many consumers in standby could hardly measure, I decided this product from ELV to buy. I can only say: I have no regrets. The device reliably measures even the smallest consumption. So I have come many sinners on the current track, although insignificant but appear to add up to in ten to twenty euros. It is particularly convenient that one can deposit his electricity tariff and based on the recording time extrapolation annualized may be carried out in euros. Very handy to determine average useful life (eg when TV, running not the whole day). Unrestricted recommendation - even though it's 20 more expensive.
