Pros & Cons
Pros
The back-lit screen shows up nice and crip. It's brightly and sizeable. I like that these are readable with the backlight off.
Kill-a-watt device is great for testing new solar panels or finding the best location for the panels. Blue back light makes the readings very visible even in a dark area as i am planning to use this on my solar panel project in my shed. Tells me how m... Read More
The resistance to measure the current is a built-in smd resistor of only 2mohm, so the voltage drop is very low. The accuracy seems to be there at least for my testing range, and it seemed to agree with the numbers my bench power supply was putting ou... Read More
Only recommendation i would make to manufacturer is to make holes little bigger for the wires. This places the neutral next to the ct wire, less chances of shorting or arcing. I have these installed on circuits used to charge my ev. My l2 charger is o... Read More
Cons
I like the size of the font, the blue backlight, wiring diagram and simplicity of it, but it just isn't accurate after 3 weeks of use. The flaw is that it puts 220 volts into the ct wires. This is a serious manufacturing flaw or unacceptable design.

I didn’t take the protective plastic off the display and was still impressed with the clarity.

Price
Over all this is a great product at a reasonable price.
Packaging/appearance
Enlarging the hole slightly cured the problem.
Competitiveness
To my amazement, these worked exactly as i had hoped and i'm now using them to monitor my amplifiers in my competition car audio system.
On a 50amp service you have two power circuit s so yes i put in on each leg.
My l2 charger is on a 240v 40amp circuit and the l1 charger is on a standard 120v 20amp circuit.

By definition these should not work for what i'm using them for.

I don't claim that they are dead on but i will say i have yet to prove the readings wrong.

I just purchased 4 meters and tested all 4 upon receipt using a dummy load.

The backlight is not on a timer so it will stay on unless you set it to off.

As it mentions in the description, it will remember if the setting for the backlight is on or off even if there is a power outage.

The overload alarm function flashes the backlight on and off.
