So far I am happy with the quality of the bands.  Some people complained that having only 2 handles was a problem, but I figure that I will not be changing weight all that often anyway.  I use them for pullups and dips for my young boys. They can't really do many if any pullups without some assistance.  I like the clips because then you can clip them to the pullup bar instead of using the handles at all and then they don't get in the way of where I put my hands.
