super bands

It's a nice set, in which everything is really doing what it takes. However, in the two smaller bands, the handles are not fixed, so they can easily slip in use and in the ring, the locking points of the band are free, for example. Then you see that the two ends of the rubber band to close only a small piece are inserted into each other. So far, they keep with me but good, and I can not trust all this construction ...
Is also very nice that a small guide with 12 different exercises is begelegt and the tapes also be delivered in a practical, transparent pocket where you can retain your them.
