I recently owned by the Philips Hair clipper 9000th At once I was out of the design and the steep devices convinced. The device makes a very finished idea, however, is only visually as a aluminum case, plastic is processed here .... but what can not be negatively interpreted. The wheel to adjust the cutting length is practical and very smooth rolling. The razor will be three cutting attachments, these are my only gripe with the razor. I find these are not very stable built ... I fear that if the unit time slips as the sink, something might break. I leave here, of course, like to convince you otherwise (it is just my opinion). For proper and important as far as the hair trimmer, namely the function .... I sat down with the unit now apart and tested it in two functions important to me. What is to be mentioned positively ... the hair trimmer is not too loud. The blades sharpen themselves what the longevity of the hair clipper does well. At first the neck from Bart: Here the Philips makes a good impression, it cuts clean and pleasant. I had the pluck them up with other devices often problems hair. The job at Bart has passed with flying colors the 9000 clean and Philips. Now there were also the hair off: Here I went to the side and have shortened this .... to my surprise this was also clean and fast, no cracking hardly the correct requirements. The cleaning is super easy, just break down the top and the cutting unit and edit with the brush (here it would be nice if you could rinse it, but the device is not waterproof) I am convinced of the device, it can fully (essays will tell if I am right in my doubts about the stability) recommend cutting results are top .... the beard can be wonderfully clipped, perfect for my purposes! Of course, there are devices that are cheaper, but this hair trimmer is worth the money in any case.
