OEM cables that come with devices (or as post-purchase accessory) are typically crap (they fray just looking at them) and never last, but it seems like most third-party cables aren't much better - they either just stop working after a while, or don't stand up to regular use (seem to easily break due to normal 'bending' of the cable during use).
Are there really good quality device charging cables out there? What do you use?
