I bought it because I have not found a USB cable that has a right angle plug and is so flexible that my smartphone is not dragged around by the charging cable. Meanwhile, I have two of them: The first time I immediately removed the reel mechanism, because I use it for the travel charger's SmartPhone. You win by almost 10 cm (then about 75 cm total length). That's enough most of the socket to a deposition site for mobile phones and the retractor does not interfere when packing. On the second, I have to reel drangelassen: It is in the desk drawer for times just to connect USB devices to your PC. For example, ext. Hard drive. CONCLUSION: Highly flexible cable. Optimal length would be 1.20m.
