 Great features, but could use improvements November 22, 2008
This is a great little device with a lot of features for the price. I bought the device to see how much power my 40" LCD tv, amp, and PS3 were drawing.
The only problem I have with this device is that the screen, despite the large size of the numbers, is difficult to read due to really low contrast. You have to view it from just the right angle, and usually with the aid of a flashlight. This is really hard to do when you have baseboard-mounted outlets like I have.
I would be curious to know if this screen contrast issue is a common problem, or if I may have a defective unit. At any rate, better screen contrast and a back-light would make this a perfect little power monitoring tool.
 Electricity costs November 22, 2008
Great product for determining which appliances are the most costly to operate. Very reasonably priced,fast delivery.
Measuring Electrical Values November 17, 2008
The instrument arrived well packaged in perfect condition. Exactly what I expected. I am very pleased with the features. Simply to use. The small one page "manual" that came with it is very clear. Is very important to use it with the "Power Strip Liberator" (a short cord extension) in some crowded places where could be difficult to read the screen on the instrument.
Works as advertised, highly recommended November 11, 2008

With rising energy costs, I wanted to know where my Kilowatt Hours were going to, this product has helped immensely. If it plugs into a wall, it can be plugged into this unit. I would leave it attached to various appliance for a few days each to see how much energy each device was consuming.
Highly recommended!
Good product, do the expected work. November 9, 2008
This product works as expected. I purchased this unit to make an analisis about parasit power consumption in my electronic appliances in home.
I discover the following:
- the lcd requires 180 ~ 230 watts. After going to standby or shutdown, the tv use 60 watts for 3 minutes. This is to cool down the lcd lamp for protection (fans and additional circuit works for this time). Can be a mistake if I remove the AC cable power or enterely shutdown the tv without allow this process to finish. Good discover. After this 3 minutes, the standby mode on the monitor only requires 05. to 1w.
- my motorola cable system requires the same ammount of power (27 ~ 30 watts) no matter if this unit is ON or off!!!!... all the time is fully powered (because have an internal hard drive). But I believe (wrong!) this unit must save about 50% if is off.. but no!!!!
- the blackberry / sony ericson chargers do not drain any power (0W) from AC if the phone itself is not connected. I DON't need to disconect this chargers from the outlets.
- My APC Smart UPS 1500 drain 30 WATTS! even when is completely turned off!!!Is better to disconnect this unit from the ac cable!!! amazing!...
- My pc (dimension 9150) is a power hungry pc. Because have pentium D (first edition) who requires a lot of power. This pc requires 230 watts but when I play Command Conquer (3D real time strategy) and because I have a HD2900 ATI High Definition card who requires 650 watts PSU. Interesting: when I play the game the power rise from 230 to 300~320 watts!!!!
This unit is very usefull to understand how the electronic systems works and if are energy efficient and how you must manage this units to save power and money.
Highly recommended, is cheap and you can check your ac freq and exact voltage (i have 128 volts from 127 expected in the ac line)......
enjoy and sorry my english
