The hair dryer does not require a processing perspective, a decent, stable impression. The screw to clean the filter is not a cheap plastic, but a proper screw - you need so do not be afraid that when used as quickly breaks something. The power of the blow dryer in the form of the amount of air it is moving really well! At level 1 (right button down) corresponding to the power in about a commercial hair dryer for pet owners. At Level 2 (right switch up) the performance is significantly increased! Since you realize the power that has the device! The right switch to middle position corresponds to the switching off of the fan. From the "breath power" fro the device thus meets our expectations. Now the (tolerable) shortcoming: The heating of the instrument is similar from the switch here (left button). Switch up -> full heating capacity (far too hot for my taste for every dog!) Switch down -> Normal heating (in winter is possibly useful, but still too hot for my taste!) Switch in the middle, however, should switch off the heating and supply only cold air. However (Light-emitting diode, which indicates whether heated or not is then out though, but nevertheless comes hot air. This hot air is for dogs OK, as long as you do not based directly on the skin, leaving there at one point. Since not accompanied by instructions in principle (only one illustrated, English instructions for cleaning - but no indication of switch position, etc) I can not explain why even when the heater hot air comes and is the unit to be very warm (you do not burn yourself but the device is significantly warm). Therefore deduction of points. From the volume ago the instrument is contrary to the description very loud! In the aforementioned 50 dB a conversation between 2 people should still work - this is definitely not in the unit. One would cry just for one to understand something. The volume is roughly comparable to that of a vacuum cleaner at filling stations etc. Thus, the volume is bearable ... though not as quiet as described. Recommendable All in all for the price!
