Property me this unit gained for the home after I had trained for a spa stay every day with a rowing machine. I did not find it so exhausting (ok, am not a high-performance athletes and doing your own pace but persistent) and totally effective. The calories consumed tumbled on the display. Once home, I did so immediately browsed at Amazon and have become aware of this device. Reviews have been studied, the price was fine and it was ordered. It was delivered very quickly built and studied ....... the display. I found it personally very confusing how what (trains, calories burned, time, etc.) and adjusts must confess, really I have it to this day - not understood - after 2 months. Thankfully it went my family so well, so I did not have to doubt me. Of course, this unit is not comparable for this price with a rowing machine from the fitness center, which will cost more than loose 5 times and more times. You can adjust the difficulty level in 5 steps. But somehow it trained uncomfortably and goes with me on his back. I can not say why, especially since I did not had this problem in the course of treatment. Thus, hand me 15-20 min. Training of. Nevertheless, it is effective to take away little space and is really not bad to spend a few days a week to move.
