Shock cord inside poles of freestanding tent became weak

Remember someone here complained about the shock cord in his MSR Hubba Hubba NX poles went weak over the course of one or two years.
Now the same happened to my Exped Venus 2, after one year the shock cords were almost out of function. When taking a careful look at the cord it looks like the rubber inside partially broke.

Had been at the vendor yesterday, and they replaced the cords no question.
They said that "obviously there was one delivery of cheap Chinese crap" which might have affected several tent manufacturers.
Just wondering if more hikers here might be affected?

I have replaced shockcord by buying a coil of it online and taking poles apart, tieing knots in the ends of cord and threading it thru the poles.

The shock cords failing was especially bad with the Venus, as this tent has sleeves where the poles need to get pushed through at tent setup (that works even with a bad cord), and taking down the tent was a nightmare as at the lightest pull on end pulled the joints apart and the poles seemd to never come free off the sleeve.
The lady in the shop gave me a good length of shock cord for free and I will repair the poles the next days.

Later:
Changing the shock cord was easy, using a welders vise-grip locking pliers.
Pretty strong, the new cord.
