So, guys. It's my first device of this type. I've seen a few videos about it and made my decision.
Overall - the impression is good, neat assembly. But I expected "feet" to be a bit more spongy. They are almost hard. Next - if it is your first experience, spend time for proper adjustment. I pushed knee holders out as far as I could. Otherwise, my legs were going to the sides. Maybe I will play a bit with springs, I feel I'd like them to be harder. And to be honest - the first time is terribly scary :)
