Handy Little Item
Bought this item and tried it, It seems to work very well. I read a post complaining that the timer etc started as soon as it was plugged in....well, it does do that, but the instructions say to push the RESET key to start the readings from zero. The only downside is I wish it had a battery so you could unplug the unit and the item you're testing to easier look at your readings. (Some things I tested cover the readings while testing) I don't have a huge use for it, but it is very interesting to compare what different items use power wise. This model is better than the cheaper model because of the more detailed power consumption / cost calculations it does. Glad I bought this unit.

Works great; fast results.
I was amazed at some of the things I found around the house that draw power just sitting there doing nothing. This thing is easy to figure out and program in your cost per Kwh.

A couple of things I found by using this device:
-- the entertainment center costs me $11 a year to have just sit there in standby mode. This is a 32" LCD TV, surroundsound system, DVD player, Wii, and subwoofer all plugged into a Monster HTS 1000 MKIII PowerCenter with Clean Power Stage 2 (8 AC outlet, 2 coax, phone & network). If I watch a DVD or play the Wii, it costs me 40 cents a day, or about 3.33 cents an hour.
-- My gaming computer (Dual Core, 500 watt power supply and 19" LCD) cost me $99 a year to run 24 hours a day, 6 days a week. That includes the occasional laser printing and occasional 2.1 speaker usage. So I turn it off more often.
-- Cell phone charger: .86 cents a year, but when charging it costs me $1.73 a year.
-- New coffee pot costs me between 5-7 cents to brew a pot of coffee and let it sit for a couple hours.
-- Toaster at 350-degrees costs me about 11 cents an hour.
-- Dell laptop charger costs me about $1.70 a year to keep it plugged in. It's about a penny and hour to charge the laptop's battery.
-- NOAA handheld weather radio costs 86 cents a year to run 24/7

In the end, it seems like it is only really worth the trouble to unplug the entertainment center when not in use and turn off the computer more often. Sure, everything draws power, but we factored in the hassle of it versus the cost.

We have been unplugging stuff around the house when we are not using it, and began to wonder how much we are saving. This thing has helped out in deciding what's worth going through the hassle of unplugging each time, and the results are almost instantaneous. I highly recommend using this device to settle the score in the fight against wasted energy usage or even in helping decide which devices/appliances around your house aren't worth owning due to ridiculous power draws.

I'm still testing more items around the house, so check back later for updates.

Useful concept but product arrived defective
The P3 International P4460 electricity usage monitor is a cool idea and a potentially useful device, but to my disappointment, mine arrived with a major defect: the second-rightmost digit in the LED display doesn't work. So I can't discern the number the device is displaying. This defect affects all of the device's operating modes equally. Now I will have to get the defective unit replaced. I'll reserve my final rating until I see a fully functional unit.

By the way, as others have pointed out, the lack of power cord and a difficult-to-read display (due to lack of backlighting) are shortcomings of the product, along with certain other inconveniences reported in some of the reviews. Personally, I can live with these problems, but I can't live with the display defect my particular unit has. The display visibility problem can, at worst, be remedied by shining a flashlight on the display. The lack of a power cord and the limitations with respect to being able to plug the unit into some outlets (due to its size and shape) can be addressed by using a short, 3-conductor extension cord between the P4460 and the wall or other outlet. I have a little extension cord that's about 15 inches long -- perfect for this application.
