When I first bought them (the ones that came with cables) 2 out of 3 micro USB ports failed in less than a year. It might sound terrible, but to be honest, I love the convenience so much that I think it's worth it. I know it seems odd that I'm still giving it a relatively high score, but I think it's pretty good for that stat. I really like what this cable has to offer and am more than happy to pay this random fee for these things. Also because it looks like it was just a weird accident. I'm fine with most of the other connectors, and it's nice to be able to easily swap out these cables. But I mean, the thing works, so there's not much more to say.
