I had been around for years, the Dyson AM03 eingen in operation and now the successor Dyson AM08 Cool also in use. The AM08 is a very well-done further from AM03. The Dyson AM08 Cool much quieter in operation, mainly in the high rotational speeds of the engine is the noise reduction clearly audible. Compared to the usual wing fans is a clear advantage that the Zerhackgeräusch the air is eliminated by the wings. One hears only a fine streams of air. New to the Dyson AM08 Cool is the advanced remote control that now besides switching on and off and the oscillation (rotational movement) also includes a new timer function, with which you can leave automatically turn off the fan in stages between 15 minutes and 9 hours. A very useful addition compared to the AM03 that this had not. So you can, for example at night run with this switch the fan and he then turns eastward again automatically. Also new and a nice addition is a digital display in feet, which indicates the strength of ventilation incorporated place between 1-9. The predecessor AM03 this had not, but he had also at the foot of a knob, with which one could manually adjust the amount. Who has fallen off the AM08. Here you have to adjust the strength to stay on the power button and then the strength counts up and down. Then just let go at the desired thickness. The oscillation can, however, turn on and off via the remote control. Bad on the remote control, both the Dyson AM08 Cool, as well as its predecessor AM03, is that you have to align relatively accurately on the device when it operated remotely. Here, the receiver could be performed much more sensitive. Overall, however, the unit deserves 5 stars. However, a star I pull from for my opinion extremely high purchase price from the current 400 EUR. For this, however, you get at least a properly processed unit of solid materials.
