I am not a professional. I used it for amateur work at home. At first, I bought a cheap wheel and it broke after cutting a meter of cement. So I decided to get something good. It is powerful, has no vibrations, starts quietly, and the build quality is excellent. Some secondary features that could be improved are as follows. For my physical condition and age, it is a bit heavy. I would also prefer a four-meter cable instead of a two-and-a-half-meter one, and perhaps the rear handle could be rotatable.
