From the functions I was very surprised: it not only shows the Watt, but also voltage, amperage, low consumption and high consumption, plus heart, uptime, and cost kWh (adjustable) (eg in standby a device.). In the latter case you have to be careful, however, because everything is in cents (not in) indicated. Alternatively you can also enter in, however, makes it for the odd electricity prices makes little sense. So fall in eg. 0.2642 / kWh the 0,42Ct just gone.
Very nice is also the ease of use: the display is huge and up on the cost of electricity, there is nothing to adjust. It is a pity that the resetting of the data, unfortunately, the price of electricity is lost as selective deletion would have been nicer. Since entering the cost is very simple and fast feasible, but lets see over it. Also, the device has got very bulky, which is justified by the large display, but with many ads.
Conclusion: For little money you get a good instrument here. Ideal to unmask power-hungry or simply to determine the personal consumption. By specifying kWh and operating time can be effectively calculate the annual consumption: A device for one day measure and then take 365 times. Simple and good! The resulting electricity costs can also be seen at a glance. A simple operation allows laymen to be able to exploit fully the equipment.
