I bought this elliptical machines especially on request of my wife. At first we were a little put off by the price though, but due to numerous positive reviews and test reports, we then still "slammed" and were not disappointed. The building was totally uncomplicated and was mastered by me alone. For 5 weeks, the CTR3 is now almost every day in use - without any quirks. The training programs and difficulty levels ranging from completely so far and will be sufficiently well over the years. The ability to deal with real routes via software and Internet, we have not yet been tried - still a nice option. Compared to the cross trainers in a gym of the CTR3 is much smaller, but certainly no worse. Many years of experience, I would say even, purely from the price / performance ratio even better and much quieter (could also be placed in the living room without any problems, without disturbing others). As a conclusion we can, based on our experience, only for sale guess this CTR3.
