First of all, I must admit to initiate fair to say that I can not verify whether the display is exactly, but I assume and will explain that too. I had been a Stromverbrauchsmessgeät the construction market in action, which, however, only from about 5 watts consumption indicates a performance. When I now had my two new LED Christmas lights that had ever 1.2W according to the manufacturer measured, showed a lot to me that this cheap device has displayed from the hardware store already 11 watts. Then I decided to initial purchase of this product from X4-Tech. When I received the device and I had reconnected the chain shows that new consumption meter actually 1.2 watts for a chain, and 2.4 for both chains. So I'm assuming that the accuracy of fit even at low power levels. I can say that it is easy to use and also has a large LCD display, which is not illuminated to the device itself. That would be perhaps the only shortcoming. But for that I want to pull anything. Yes and the device looks different, as shown in the illustration. The three keys are not vertically but horizontally mounted. From me there for a strong buy recommendation.
