I have a love-hate relationship with retractable cables. I love the convenience of not having to carry around long cables and twist ties to keep my devices charged. I especially love not having cable mess all over my truck to keep things charged on the go. However, I hate that nearly all retractable cables are terrible quality. They are too thin to charge well, which kills the convenience when you have to leave your phone plugged in for hours to accomplish anything. Plus, the retractable mechanism always fails in a week or so either not retracting anymore, or unable to lock out (always retracting).
So far, these have been surprisingly great quality! The cables don't look any thicker than others I've used, but they charge just as well as any other data cable I've got. They don't fast charge like the heavier cables do, but they weren't designed for that. They work as they should, though.
The retracting mechanism seems to be decent quality, too. I really abused them over Labor Day weekend by using them in a UTV out riding on very dusty trails. They got so caked with dust that they wouldn't retract anymore. However, unlike any others I've used, after taking out the one screw that holds it together, I was able to clean it, add a couple drops of lube, and it works perfectly again. They're out in my truck working fine right now. I've tried that with others in the past, and never been successful before.
PROS: Far better than average quality Reliable Durable Great price
Survived over 500 miles on bumpy roads in Michigan on the motorcycle. It has done what it needs to and keep my phone charged throughout. Haven't had any issues with the retractable mechanism. This was a feature that I liked so that as I position my phone on my phone holder I don't have excessive amounts of cable to deal with. So far so good.
My wife is the USB cable monster. She continuously looses them, breaks them, and etc. I bought her a four pack for Valentines day. Now she has one for all the places that she would need then and never needs to move them.
