Since this is my first scroll saw I can unfortunately not make comparisons with other models. Who but first look at one / two videos to and on the sound of the saw blades tensioned respects noted that these must be good quality and no tearing even equal.
The guide is really to use only the light from the waste.
The scope of delivery as indicated + Allen key because it fits without any function in the supplied screws. (The from the "key Garage" fits it all in Allen screws)
So far I am thrilled and should it start I will everyone to know it.
