I bought this band set just over 2 years ago and I guess I've been too busy using them to write a proper review.  I take these bands with me literally everywhere.  They live in my bag and when I get bored or need a quick stress reliever, I pop them out and enjoy a little workout.  The build quality on these bands is really top notch.  The rubber has not weathered at all in the two years I have owned them and I cannot see any cracking of any kind.  The handles have good foam padding that shows little to no signs of wear from daily use.
