I bought two of these Micro USB/USB cables. The manufacture quality of these items was pretty good. The first reason was because I was tired of wrapping my charging cables up when I travel around. I use the same AC/USB adapter that came with my phone, but this winds up nicely and fits in a small pocket on the side of my gym bag. The second reason is that I damage the regular charging cables when I get in and out of my truck. With this cable, when I am done charging my phone, it gets wound back up and can't get damaged. After reading a few other reviews, I have to agree that sometimes it doesn't wind back up right away, but with a little bit of tinkering it always winds back up. Bottom line: it's a cheap (money-wise) charging cable that does it's job. One suggestion: if purchasing this product for use in a vehicle, make sure you have or purchase a cigarette lighter adapter that fits snugly into the cigarette lighter; if not, you will get frustrated when the cord doesn't wind back up right away and you constantly pull the adapter out of the socket. As of this review, I have had them for about 2 months and have not had any problems at all.
