It works well. I did not have a problem with it slipping on my desktop, and the tension adjustment does adjust the tension. I didn't give it an excellent rating because 1) after I unpacked and assembled with it, I had to fiddle with it to unjam it, and 2) the tension does not adjust to a light enough tension for early physiotherapy needs. But it works fine for my current needs.
