Positive: It does its job in a satisfactory amount of time, depending on the quality of the blade, of course.
Negative: Excessive noise, which may be due to the powerful motor.
P.S.: I have read from many people that the mesh is sensitive and breaks easily, but I completely disagree. Technique matters, not strength. Strength is not needed at all. If you apply too much pressure, it will break. It doesn't require a nuclear physicist's brain. A mesh lasts me almost three years

Strong like a machine but the mesh is terrible. I have had it for a year and I have changed the mesh 3 times. If the mesh doesn't improve, as a professional of many years, I would not recommend it. Stay away

Very good tool but faulty. In professional use, the front grill constantly breaks! Stay away!!
