Anybody notice this? All of the eBay/cheapo charge/sync cables and car-chargers I've bought over the years (probably a dozen between all my iPhones over the years) have all stopped working within a few months of getting them. Now, some of them where so thin that they broke on the ends and frayed and this is obviously why they stopped working (and frustratingly the same can be said for the stock cables, too). But even all the others with no obvious wear/fraying have done the same thing. And it's always the same process each time - work fine for several weeks/months. Then they start to cut in and out randomly. Then they just one day don't work at all. I just don't understand what would be going "wrong" with all of these sets that would make them all universally stop working.
