The Ultratec heater surprised me at first with its size, since it is relatively small but fails. With us he should be used to heat the bedroom or the bathroom. He has a good level (we used in an upright position as in the picture) and very pleasant, the sensor is set to 2 minutes. No one moved in the sensor area, the device switches off. It would be nice also if the appliance completely goes out after a while, but that does not make it. Too bad, so we need but remember to take the unit completely from the power supply again. In addition, the cable could be possibly a little longer. There is a "normal", as well as a high and low heat operation for sensor operation. Is very uncomfortable the very penetrating smell of plastic, not only the first use but also afterwards. That bothers but pretty nose.
