Myabe you have them stretched out almost to the max so that when bent
and when swung around there is even more tension on the flex areas.


"Stretching" may not be the best word to use.

The extensions are composed of many collapsed segments. To lengthen
the pipe, one or more of these segments can be un-collapsed, or
pulled apart.

But for each segment it is either all or nothing. That is, the
segment is either collapsed or pulled apart maximally. There is
no half-way or partial-way point.

It seems, however, that I am the only one experiencing this problem.

I suspect that it is the sunlight. All my extensions are
on the north side and exposed to the sun all day. Vinyl is supposed
to contain additives that resist UV but maybe these do not.

Mostly shaded here, so that could very well be the difference.

I've been using these for years in full sunlight.
