I am extremely satisfied with the machine. He came very quickly. He does exactly what I expected him to do. For proper functioning, you need to choose the right opening and set the right pressure. The advantage of the machine is that it is possible to set the correct pressure both on the side of thinner wires and on the side of thick wires/cables. Strips insulation in a sufficient range of dimensions. With new knives, it can also strip wires slightly thinner than 1 mm. Stripping a solid copper conductor with a cross-section of 10mm2 is a bit of a problem for him, but either you let the machine suffer and it will handle it, or you prefer to strip these conductors by hand with a knife. When you strip the cable wires, you have to carefully choose the right opening and the right pressure so that you don't cut the individual wires, but it can be done. This machine is ideal for DIYers who strip thinner wires/cables in smaller quantities. It is even suitable for an apartment, as it has a real electricity consumption of 60-80W (depending on the load) and is quiet (it can be made a little quieter by placing it on a foam pad that absorbs vibrations) and is easy to carry and small enough to store. This machine is also ideal to buy with https://eur.vevor.com/wire-stripping-machine-c_11523/cable-stripper-wire-stripping-machine-copper-recycle-1-5mm-25mm-p_010630760561 (I have also), which you will drive with a cordless drill for fine tuning when stripping cable wires, or for wires that you cannot adjust to given the machine... I definitely recommend this machine, you just have to learn how to work with it. It will save a lot of work and time. Too bad I didn't have it sooner. :-)A spare knife is also supplied with the machine. You can buy a new one on aliexpress, for example, according to the dimensions of the delivered one (which is 68*35*2.8) - I bought 5 pieces like this for €35.
