Just know what you're getting and be realistic that this isn't a bungee cord for your Ipod! The cables retract symmetrically from both ends, so if you just pull one side, yes, the cables will get tangled/bunched up. Pull both ends at the same time when you want to extend/retract. Also, don't yank really hard. Be gentle because the cable is thin.If you're fine with those two "drawbacks," then this is the perfect accessory for connecting your iPod to the car jack. I find this length perfect for the car, and the retractable mechanism makes it super easy to use and tidy to use while I'm driving.I almost didn't buy it after reading some of the negative feedback, but I'm glad that I took the product description objectively because it does exactly what it's supposed to do. Plus, the sound quality is fine.
