I totally seduced by this. That was ten years that I had not used mower and I managed my first cup blow smoothly and very quickly (I cut myself hair). The trimmer is powerful enough: It cleanly cut (not need a lot of passes in the same place, no weakness observed) and turbo function is very effective in the most difficult places. The guides do their job perfectly (no accident) and the wheel system is very useful (it does not move at all). The device is very light, wireless autonomy is good, which is convenient for those who cut their hair themselves. Only small problem (minimal) form is not very ergonomic and we would have liked to have a little better in hand. The storage case is pretty and practical, this is a real plus not to be overlooked.
