Excellent brand because there are
Excellent brand because there are true differences in their resistance levels of their bands. Have tried other brands and all bands in their packages seem to have loose resistance and super thin, just garbage quality. This brand has been consistent for years (meaning it hasn't cheapened the material). They don't sell on Amazon (as far as I could see) which is a GOOD thing b/c so much of Amazon stuff is crap these days. Great customer service as well.
