    Excellent item, they work very well. My only complaint would be the size of the module is too large so that you can not use the second electrical plug once you plug this into the first one.

    I never got to use this due to the difficulty in obtaining the display that goes with it, so I returned it. On the plus side though, Smarthomes customer service in sending me my refund was very prompt.

    Quick delivery. Correct product. Works very well. Thanks

    I have two of these sensors and the wireless display unit. Setup was very easy and worked exactly as described in the instructions. I'm having fun watching the displays change as different devices cycle on and off. I have an external hard drive and a router plugged into one sensor and you can watch the power usage change when the HD backs up my laptop over the wireless network. Very cool! I'm going to get more sensors!
