Digital camera reviews of P3 International P4400 Kill A Watt Electricity Usage Monitor
Digital camera Review: Kill A Watt Is More Than Advertised
Summary: 5 Stars
I bought this to determine Kw usage around the home and it really does work. I also used it to teach my 7 year old about current, voltage, and watts.
Well worth the money.
Digital camera Review: So useful... I love this gadget.
Summary: 5 Stars
I don't know how I didn't have one of these before now. It works great, the display is clear (but you may need a light to read it under a desk, or behind furniture). I've used it to see how much power my PC was using to choose an appropriate power supply, and how much money I'm spending running that old refrigerator. (By the way, my mid/high-end PC only uses about 300W so no need to waste money on a crazy 600W+ supply, and a new energy efficient fridge would pay for itself in a few years).
Well worth the money spent on it. I highly recommend it to others.
Digital camera Review: Garbage! Waste of Money.
Summary: 1 Stars
After about five uses, it started registering my household voltage as 175V and 24A on a 120V 10A refrigerator. The manufacturer said it was a calibration problem and that they would not fix the device or refund my money. They said to go after Amazon.com. What a piece of garbage with horrid support.Digital camera Review: Exceedingly useful
Summary: 5 Stars
What can I say? Buy one and use it. It yields valuable information, interspersed with the occasional "does that device *really* draw that much when it's turned off" surprise. The P4400 gives you the raw information. There is an upscale model that might save you some keystrokes on the calculator.
I have thoroughly enjoyed mine. And it has been quite genuinely useful in addition.
Delivery was prompt. No problems.
Digital camera Review: P4400 Kill A Watt
Summary: 5 Stars
Simple, effective, and cheap. A real eye-opener. Really helpful in defining a cost-benefit analysis to determine whether replacing an appliance will be cost effective. I've loaned it to several people and they think it's great, too!
