For the price you can not really complain, but I would have wished that the cable is slightly longer. I use my phone as a navigation system, and must attach some reason the left of the steering wheel. The cable is (ka as they call it) curled like a telephone cable which indeed in itself is not bad, but unfortunately there is quite stiff and can not be drawn very far apart and this creates a fairly high train on mobile. Have a little bit afraid that it is the charging socket (or whatever you call it) hurts.
Conclusion: If you use the cable for mobile phones as Navi already have to do it in the middle of the windshield mount so that the length is sufficient for mounting the left of the steering wheel, it is (at least in my car) too short.
