they look nice and they do their job

I've been eyeing these things for a while, but at $6 each how much energy are you really saving? I used a kill-o-watt monitor to find out. I tested just about every appliance that I would consider putting one of these things on. Found that most of the older devices are the ones you need to watch out for. Newer devices are NOT worth putting a switch on at all. This includes phone chargers. If you are worried about phone chargers (unless somehow your phone charger is ancient or just really cheap) stop worrying. The kill-o-watt monitor wouldn't even register any electricity usage from the phone charger no matter how long I left it plugged in.
I did not try this on any large appliances (TV, etc) since I think using it for that would be way too much of a hassle to turn on and off everyday. Devices that would be worth putting one of these on in my house is: and old DVD player, a (very) old printer and PC, an iPod speaker/docking station.
update: I now have one on my crappy router that I have to reboot once a week to keep my wifi working. Not the intended use (save electricity) but makes rebooting the thing much easier!
