For longer hair is emptied better the chamber in between, and it is also better, once freizubuersten the blade to have more suction power.
I have the device now more than two years and am extremely satisfied, especially with the fact that I can cut beard and head hair.
The only downside is that the hardware is less robust than the main unit. In the first year broke with one point in the article. That does not bother big, but does not look nice. After two years, the holder broke off for a small blue plastic part that is above the drawing-up chamber. Sucking now no longer works so well.
According to Philips, you can all the parts that can move even the users buy more. The essay is re-purchaseable, the little blue part (because you supposedly can not change yourself) not.
Thus, I will buy after two years a new device, and I'll buy the same model again.
Update: I've again bought the same model. After almost a year in turn the spring has popped out, holding the little blue plastic part in position. Again, the suction working poor and you have to remove the hair more frequently.
Perhaps still better than simply to drop in the sink and on the floor, but now it annoys me but.
