Frankly nothing wrong .. price / quality ratio .. nikel! I am more than happy .. I wait to see the result sets .. I plan to use it every day at a rate of 30 minutes per day .. we'll see if walking to the virtues inculcated him .. when I would walk at ease .. I would start the race ..
So frankly I recommend! Go ahead without thinking .. it is top notch! Roulette to move .. compact .. absolutely not noisy at all! top!
