Sounds like you are using the cables a lot . That would be plugging the
cables in betwen 3 and 10 times each day.

I don't think I'm using it any more than anyone else.
I was just guessing at the number of insertions.
It's only a couple times a day that it's used, on average.

Anyway, they failed in far fewer than 10,000 cycles, so, I'm
assuming the micro USB standard is seriously flawed, or, I'm
just getting bad cables from Frys.

Here is what Frys had today for USB cables in the components area:

So, I bought a 3 foot and 6 foot replacement:

We'll see how they fare, but, most seem to lose their nubs in
a few months like these two cables did:

The one at left is no name, the one at right has Belkin molded
on it. Maybe it's a fake? But I bought it at Frys, for sure.
