I have bought this thermostat plug in 2011 and was actually very happy (just un easy to use). But then broke despite very careful handling the sensor cables at the site directly on the device. Due to the bes ********* housing screws the opening of the unit was very cumbersome - with a lot of patience and improvisation I could patch up the cord and anchor decent on the housing. Slightly thicker and more flexible sensor cable would be super!
