Does what it says but not the best design. Yes, the product performs as advertised — it’ll display the amount of energy consumed in KW/hour, watts, volts, and amps. It just doesn’t have a very thoughtful design. Some comments:
1. As depicted in another reviewer’s photo, the unit is bulky and the top extends a bit high over the prongs — as such, it monopolizes an entire standard dual outlet requiring the user to unplug something else (probably the lamp required to see the LCD screen).
2. The LCD screen is not backlit so crouching behind a dark appliance to get a reading is a hassle.
3. It’d be nice if the unit had supplemental battery power to save the readout until you plugged it into something else (even better would be some memory to store multiple readings). The device is passive so once you unplug a device from it, the information is lost.
4. It doesn’t compute KW/hour immediately. This is a fairly simple calculation for a device like this to compute on the fly.
At a list price of $35, it should have at least some of the features listed above. As it stands, this is a primitive device in “attractive” plastic cladding.
