It maybe more expensive compared to the 1st unit I bought, its so much heavier and is like a quality coaster , so it doesnt move all over the place during use. Damit wirken sich einzelne Störatome oder Gitterfehler stärker aus. All I can comment on is the general quality, which seems to be great. The bike doesnt lean as it would with a conventional stand. Every time I use them i get compliments! These shoes are adorable and beautiful! The buttons feel nice, they do not feel wiggly. The are only small and lightweight so very comfortable to wear even for hours at a time, thankfully. ) Seriously. I switched to the Digitech thumb ball mouse and I have never look back .
