Why only 4 points? After unpacking, I noticed that the bottom, clearly too weak dimensioned locking pin had not endured the transport in the charging station and was canceled. With modeling clay, the de facto left without incurring repair tracks in order. What visually bothers me is the black power supply with its black, bell wire-thin and inflexible power cable that does not fit the look of otherwise quite useful styled shiny white charger. Also a bit unfortunate got the Saugrohrreduktion, ie extra nozzle that has been adapted inexplicably not tidy the shape of the mouth of the device (OK, that bothers probably no one but me, though I am surprised such an error in the production process of a brand manufacturer such as Philips). This is extra nozzle, and that could now be so many other also disturb a bit too short for my taste. The brush attachment in turn is precisely and practically. One problem in continuous operation could be my judge it after the choice of materials for the removable Mündungsdüse. If you regularly drawn on rough, hard surfaces (stone, tiles, etc.), the outlet opening abrades relatively quickly. Once this is white, looks accumulating in resulting grooves and scratches forcibly collecting dirt - the device is loading in the charging station that is with this suction opening up - not exactly appetizing.
Granted, these are all small things, as well as the very precise on-off slide switch which despite gumming with wet hands can not be quite so easy to move back to the off position. Still, I can recommend the device out of conviction, it is certainly one of the best currently available on the market!
