yea me too, thats hard to believe … but YYE should give you your money back 
I had the same problem. But i know from ballistic test kevlar is hard to tear but not cut it will stop a bullet but a knife will cut right through it. kevlar is far from abrasion proof all of mine frayed horribly at the finger loop
ok ill up load a picture in a few min my ipod is dead. im a first timer in the new age of yoyos today but i started yoyoing like 14 years ago but i just started again
ok the pic of the string is coming up
I really liked my 50/50 kev/poly strings I had. They are not as soft, and are kind of rough at first, they last a really long time if you don’t like changing or buying new string. I don’t do a lot of whips so I can’t comment on that. I mainly bought the kevlar strings because I didn’t want to break a string.
