When shaving with this device you have to act cautiously. To me it has already happened several times that at my chin edge of the slats Bart Schneider have bent apart and then cutting closer to my face came as desired. (See photo). This could have been solved constructively better. If, however this issue is not too strong imprints is to master.
The spacer is not able to set up my whiskers so that the specified cutting length is achieved. So in set 2mm come around 4mm out with me. Smaller and more numerous slats would have been better here. Luckily enough for me, the 2mm-setting.
Conclusion:
Overall I would recommend this beard trimmer people who want a beard to try only once. I'm going to probably soon buy a more expensive device.
