Do not buy. This meter was being used to monitor power consumption of a desktop computer (200-250 watts). The product worked fine for about four hours then the LCD screen went blank. The product still provides power to whatever is plugged in to it, but does not give any information about power usage. Spend a few extra bucks and get a better quality meter.

I paid $3.99 for this just to compare it to KillAWatt. After leaving my Frig plugged into WANF for 24days I can't figure out what it recorded. For Cost, it doesn't say whether it's recorded cost/minute, per day, per hour, per month OR WHAT!! For Consumption, it appears to record instantaneous and accumulated KWH, but it doesn't SAY what it recorded. To me the WANF unit isn't worth $4 I paid for it. The User Manual is so poorly worded it will do nothing but confuse you, so if you buy this unit you're on your own. However the KillAWatt 4460 unit tells me exactly what it's displaying in dollars/minute, per hour, per day, per month, per year and in Volts, Amps, Watts, KWH, both instantaneous and accumulated. Both WANF and KillAWatt retain data when unplugged, so you can repower them at your desk to read the data.
========Original 4star Review below is Updated above========
Very detailed User Manual, but painfully short on usable information. It's almost impossible to understand what the abbreviations are, so taking a reading for power consumption or cost per day/week/month is a real challenge.
Other than that, it's great.
The backlighting alone puts it head and shoulders above KillAWatt. When you're standing on your head in the first place trying to read these things in the outlet 12" above the floor, you don't want to have to hold a flashlight in order to see the display.
Can't figure out how to contact the manufacturer, but they say "we have set the price very low in hope that customers will consider to try this product and leave review feedback". I bought it on the cheap and like it, but it's really hard to use. Hope they read this because I'd be grateful if the maker would contact me, and send a better User Manual.

This is probably the best little power meter that you can buy. It's definitely a step above the Kill-a-Watt (not in terms of design or ergonomics, obviously, but the usability). Granted, it's a little difficult to use at first and not at all intuitive, but once you read over the instructions, it becomes a breeze.
Now to the good stuff! Backlighting is definitely a plus, especially in bad areas (dark basements, barns, etc). Also, it UPDATES EVERY SECOND, so you don't have to wait for delayed readings like you do with the Kill-a-Watt! This is probably the best feature of it. It also includes several neat perks (line voltage monitoring, etc).
Overall, highly recommended, especially for the price (I'm a graduate student on a budget..).

So far so good.
So far I have been using 1 of the units and it seems to work great but I have not tested the accuracy yet, just the durability for normal use. Read more

Excellent product, but read the fine print.
I actually was sent this wattage meter (by accident I imagine) and while I did order the more stronger meter, before buying the other model, I did some research on this product. Read more
