Description is accurate, but the compatibility of the blue socket with an europlug is not good. when the socket is fully engaged , there is not contact. the socket should be slightly disengaged to works.
Works great but the built-in "universal" socket does not work with a UK plug, meaning a UK to European adapter is required for it to control the fan/humidifier. Messaged the seller multiple times but got no response so not too sure about the customer service but the price was really good and shipping quick.
