I've often bought the same model of the brand Clatronic. The first time about 6 years ago. However, I have to say that the supply cable is getting shorter from device to device. This is the radius in which you can set up the equipment is very limited and this is a major drawback in my eyes, when you consider that the fan heater requires enough distance or air around them so that no build up of heat. Here are some numbers as clear facts: Cable length with device about 6 years old: 154 cm Cable length with device about 1 year old: 134 cm Cable length with 2 devices of Nov.2014: 121 cm
As I said, I have a mine and the same model (HL3378). What is this, I do not know. Whether Clatronic thereby saving costs? -may be. The service life is getting shorter. The previous devices have persevered for several years. Now perhaps 1 to 2 years. If so have given up the ghost, the last purchased 2 fans, I'm going to get in no case again this model. The price has been held since then also. The fan costs, depending on where you buy it, always 8-15 Euro.
