Review title: Useful product
Product review: Speaking as an electrician of 30 years (and NOT someone who has purchased this product) I'm very glad that someone has finally produced such a gadget. There's no other way to analyze electricity usage (i.e., kilowatt-hours), short of spending hundreds of dollars on equipment designed for larger and/or more sophisticated applications. But, as others have said, the device isn't an electricity-saver in and of itself. Not in the least. All it does is allow you to track how much electricity a device is using (and then you can calculate the cost, by multiplying KWH by the price listed on your electric bill). What you do with that information is up to you.
