I am SO glad I bought these!!  The bands are very comfortable to use, easy to change out, simple to store and are better quality than the ones at the gym!  Having the option to vary the workout is great, too.  Thank you for making such a great product not only easy to use but very cost effective, as well.  I've recommended these to several of my friends.
