You can buy, but are better

These resistance bands are not bad and I did draw quite often in use, but they probably do not last too long, it looks almost ausgeleihert and one side can be more for a month than the other, if I exactly centered it climb (the longest band ). In tab in the center (at gekreutzten tape) often slip ... that sucks but you can live with it. For the price you do not say bad, but there are better, what is it worth it to pay a little more.
