Replaced my old one
5 Stars
Replaced my old one
Like many others, my P3 P4400 Kill A Watt electricity usage meter started showing high voltage after plugged in for about a week. So wanted to have a try on this one. The large screen and backlight help to read easier. The viewing angle is around 110 degree, I guess. Not too bad, but can be improved. It’s able to check voltage, current, frequency, wattage, power factor, cost, and so on. I measure power and power consumption often so that I’m only concerned about these two items. I tested it by my low power led light. It read 0.5W while the defective Kill-A-Watt read 0.8W. I knew the correct value should be 0.4~0.5W, so it seems to work. Also I found it could record the minimum and maximum wattage in the process of measurement. Such function will be really useful for me. I usually check devices under 100W. This meter should work for me, I think. Give it five stars for now.

3.0 out of 5 stars Cannot Read Display When Looking from the Top, Can Only View From Straight or Bottom
Reviewed in the United States on December 2, 2017
Screen visibility is bad from the top angle. From the bottom angle or straight on it reads just fine. This makes it extremely difficult to use from the wall outlet, the best way to use this is to add an extension cord so that you can actually read the screen. Take a look at the photo and you will see the various different viewing angles and how it displays. The viewing issue is the same even when the backlight is on.

For a few bucks more you can get a name brand version that doesn't seem to have issues with the display.

I haven't truly tested the ability to measure values like other reviewers have, the values seem feasible so I'll trust the baseline testing other reviewers have already done.
