Review title: A neat device
Product review: It is very cool and tells you a lot about how your devices work on your power system beyond simply measuring power consumption. It is not the expensive models, so you will have to be able to calculate the cost of the power from the kWh, which can be done with a single glance at your power bill.Biggest downside is that it has a 120volt, 15amp maximum, so you often cannot measure things like your oven/range, heating, and washer/dryer: the things that use the most power. It is also true that it will occupy the space of two outlets (or more on a power strip) while only using one.
