The thing is about the limit, I have now become just cut a whole lot with it since September 2013. Unbelievable how quickly and easily you can work with it, there comes no other saw with especially one's just not instructed that the workpiece is flat or just like the example at Kapp saw the case. And Marking with angle is also past, somewhere a point sufficient and Schnittergebniß is great. One should make sure that you do the very first section empty, is also so in the description, I have not done so and therefore the red splinterguard edge is partially pulled out something. I use it a lot with extraction (connected to an older Kärcher) and that works very well, the included angle nozzle is optimally suited. All that is shown on the YouTube video is in real life. The operation is really easy and the Systener case well thought. The blade that was there is good, but I have myself, the other two are still available to buy. At first I thought that the return mechanism, which is implemented by a rubber, will not last long, that was probably a mistake. Whether the machine is worth the money ??? Yes, in any case
