The range of functions is, in my view in order. What you need to know is that the device in case of power failure or pull out will lose all measured data (current threshold price is maintained). Personally, I see there is not really a disadvantage. On many devices, it is also not necessary to monitor the power consumption over a longer period. Since it is sufficient actually if you take a short look at the power consumption. For devices that irregular power it is consuming differently, but as it goes really well with the many power meter for a few days to let inside and then extrapolate. Who should use the equipment to really should record the consumption over a longer period, the values of course write regularly. What would also be mentioned yet is that you can read the display from the side badly. One has there ever stoop to read it. For the price I expected but also so small blemishes.
As for the accuracy of course you can also make a bad statement. My subjective impression is that the accuracy is not really what is to be suspended. All values I've ever measured were conclusive and agreed with other measurements from people on the Internet match. Since one should rely more on the experience of people or on reviews then possibly. I personally would KD-302 recommended as it will be very accurate for measurements under 1W and I wanted to measure quite a lot of equipment with low consumption. The impression has been confirmed with me (subjectively). In addition, accuracy always something depends on the application.
I personally am of the opinion that I got a good device with good features for the money, which is very well tailored for typical consumers in households. So that you can feel on consumers and can also tidy save money. The cost of the equipment I had at least without major changes after 4 months out and just as I had the whole computer stuff in the house looked at times short again. If you have a power meter in hand, to catch any interested per se for electricity consumption. But the point is enough for me that every household should have such a device.
