If you are looking for a iPhone/iPod cable that is cheap and equally as effective, look no futher. This product works as good as an Apple cable.
Con:
My only complaint is that the cable itself is a little stiff. The Apple version of the cable is more bendable.. this cable wants to stay in its packaged shape.
Pro or Con:
The release buttons on the sides of the cable also require a little more of a squeeze than the Apple version (the apple version often just comes off if you tug it). This can be seen as a good thing though, if you had problems with the Apple cable slipping out of your iPhone/iPod.
Pro:
Speed of Upload/Syncing were unaffected by the cable. The cable charges the iPhone/iPod at the normal speed. I haven't noticed any negative effects on data transfer. This is a Pro because you get the same reliability for a cheaper price.
So if you don't mind that the cable wire is ridged, this will definitely be a great purchase.
