Bests & Worsts Reviews from Amazon

We have had two Wemo mini smart plugs (Model F7C063) for several months and just purchased two more on Amazon. While we were eating lunch in the same room with one of the plugs, we smelled smoke. The oldest plug (bought last December on Amazon) started smoking and melted a hole through the top right side (half way between hot line plug and receptacle). At the time the 40-watt CFL lamp that was plugged into the Wemo was not on. There is no water in the area and no one touched the Wemo mini, which was plugged in a Belkin power strip. The only other fixture plugged into the power strip was an iPhone charger, which was not damaged. I have checked the polarity and grounding of the power strip, the outlet that it was plugged into, and the lamp. All three are fine. I sent a picture of the burnt smart plug to WemoCares@Belkin.com, but have not yet received a reply. None of the excuses given on the Wemo community website can explain the overheating, which occurred inside the Wemo mini itself. We were very fortunate that the incident occurred during the day and that we were nearby to smell it before a serious fire started. What assurances do we have that it won’t happen to our other three Wemo smart plugs we have purchased? A SERIOUS FIRE-HAZARD CONCERN.
