For almost 6 months I use this device. At first it was intended to be a bridging of Winter Jogging pause. Meanwhile I train 4 times a week and feel honored me with it, and see it as a viable alternative to work. The accumulated through years of jogging niggles, such as back pain, joint and knee pain have disappeared. The device runs completely around and virtually noiseless. I would like to highlight the service. This responds to requests in a flash and uncomplicated. Made in Germany makes it pay.
