not top! 131

Hello,
I was disappointed by the appearance of the device that does not seem very solid (to see later), to which is the mat for the knees, it is all just "ridiculous" (a card would also many do) .So in conclusion I am not happy with my purchase especially when I tried there was a crack in the wheel level and handles up to were super hard to put .In case or break it, I will post here.
