I knew the step already made a studio. The quality was therefore as expected super. However, unfortunately, no guidance was why I had to look only on the Internet, how to adjust the height. The DVD is for me also not appealing, it is out of date, not just suitable for beginners and for me also not really appealing. But various video platforms offer so one or the other video so. The Step is great, looks great, and everything fits, simply because of the lack of instructions and the DVD I have deducted a star.
