First of all it must be said that in addition to the Winders nor other accessories are required: a cutting mat to Skåne work surface and a rectilinear guide nor a metal ruler. Luckily I had already both at home and so no high cost ...
The slitter has a good appearance and is safe in the hand. The color I also like - I like it when my work utensils are in color, it's more fun to work with!
Using a slider beneath the blade can be a blade guard back and push away. This is important because the circular blade is very sharp!
On the back you can adjust the voltage or the strength of the blade - according to the material thickness. I think that's good, so you have to apply etc. not necessarily more power for several layers of fabric.
In summary it can be said that I have very good optics and confident operation.
