The coach body is a quality instrument whose robustness seems undeniable. The value for money is excellent. Operation is simple and the sound of the seat on the rail is fairly quiet. Two minor complaints: the 5 positions offered to graduate the difficulty level voltage are not sufficiently differentiated. Even in position 5 development remains easy. installation is relatively simple if one refers to the diagrams but all the installation instructions are in German which is somewhat annoying. To understand the functions displayed by the screen I had to do a translation on Google translation .... However I recommend the purchase of this product (incidentally manufactured in China and not in Germany)
