Just one thing to note about the Kill-o-watt. I've read that even though they are rated for up to 15 amps, they can burn out if used with something like a electric heater even if it draws 12 amps. I've never used mine for large loads except for a quick test on a coffee maker which does draw 12 amps. I didn't leave it running while plugged into the meter, just did a test to see how many amps if used at various settings. I did the same thing with a couple electric heaters, only testing their draw so the meter was only under load for a short period of time. Don't know if the reported failures were from people leaving the meter between a heater and the outlet for extended periods of time.
