Super shaving head, but for me as a beard trimmer unusable

I wanted to use the Philips QG3340 Beard Trimmer than a 3-5 day growth of beard. The shaving head and the processing of the device are wonderful, but I've been using the comb attachments so my problems. The material of the comb attachments feels as if it might break in his hands as much.

But the main problem is the shape of the comb attachments:
When I did not quite straight (at 90 degrees) stopped shaving the beard trimmer, were quickly made some 4mm stubble, 1mm stubble. This can happen because the Kammausätze the shaving head is not completely inside.

I would like to mention the beard trimmer shaved beautifully, but I want to be able to shave quickly and not always pay attention precisely to the "shaving" once. So I took the perfect Amaazon Return service is available ...
