The grip is very good. The heights of variables cuts (0.5 mm without grid then 1mm to 1cm with the grid), you get the assurance of mowing as you want.
One thing is sure: the terribly efficient blades accelerate your shave.
You can carve your desires.
The grid in turn (shaving) is less convincing but has a very respectable result for those who choose to shave their beards by providing a neat finish.
Negatives of this mower: charges only on its support (you can not connect directly to the razor wire) and is not practical for the trip (rather bulky appearance).
Appraisal: a devilishly effective mowing, but a less convincing shave, inconvenient to take him on a trip (large object).
