The Kill-A-Watt meter changed my life. Not dramatically. Not like a marriage or a child. But it saved me $200 a year. I plugged it into my garage fridge first. That old fridge was costing me $315 a year. I almost fell off my stool. I unplugged it that day. My beer went into the kitchen fridge. The garage fridge went to the dump.
