Mint cutting tool with defects

My old Grundig cutter is over 15 years old and a new shearing blade would have cost to 40. So I slammed on cybermonday and bought a new device for little more. Conclusion:
+ Cutting capacity prima (is also new)
+ Adjustability possible in smallest sections
+ Good battery mode (my old unit I ever had with "leash" operate)
+ Cutting speed adjustable - which is fine in difficult places such as behind the ear
+ Attachment combs can be easily replaced (the old was not so)

Unfortunately there are also some negative points
- The cut hair collects (at least for a little thick unruly hair) into the cutting ridges. So you have in the meantime removing the cutting comb and exempt from the hairball.

- Main negative point! The setting of the hair length adjusted during cutting, even though you have saved with the "lock sign". I mean, that happens when you something impresses too ?! Electronics is just not all! That could not happen with my old mechanically adjustable device. Bad is that if you own the hair cuts, then you can not see it! Only if you have the "hole" in mind. I cut my husband's hair and wake up now like a hawk on the setting - there is no problem. But such a thing should not happen - there are two star deduction.

For the normal price the instrument would have been significantly over-priced, but if the value for money is ok
