It took me a while to find a 6 foot cable that would both charge my laptop and drive an external monitor. But now that I've found that I'm very happy with it. It's just a cable so not much to say about it but the build quality seems good enough and I haven't had any issues with it. I'm very careful with this as other Thunderbolt cables I've had have worn so much over time that they no longer work. Since this cable isn't cheap, I really don't want to spoil it.
