You can figure out your electrical expenses by the hour, day, week, month, even an entire year. Monitor the quality of your power by displaying Voltage, Line Frequency, and Power Factor.

Above is the pitch, so how does each perform?

As far as giving highly accurate power readings I found that both did an excellent job, each easy to use, easy to read the results with the large LCD displays.

Each comes with very detailed instructions, excellent POP display packaging that looks good and is loaded with useful information.

All you need to do is plug your KILL A WATT into an outlet, plug the appliance into the KILL A WATT choose your test and instantly you have the results!

The KILL A WATT is a more basic unit that is super easy to use with its simple clearly labeled functions that make this the ideal tool for spot checking things while the EZ is more scaled towards the full time monitoring of an appliance as it can calculate power use and forecast power use based on weeks, months and years and because the EZ has a battery backup, you won't loose your information if power is interrupted.

Pricing for the KILL A WATT starts at $25.00 and the EZ from $59.00 and both are products that will not only pay for themselves quickly but they will last a very long time with minimal care.
