Let me get my first gripe out of the way, then I will reign praise. The Sinch costs a bit too much at $15.99. Maybe $9.99 or less would be more fitting?
Now let me tell you why I love The Sinch, it works, it works well. It works well because unlike many of the other solutions out there, it attaches to your phone via the earphone jack. This means it is always there when you need it and you don't have to carry an additional gadget. Also, it doesn't force you to wrap your cord the same every time, wrap it how you like and then flip the magnetic holder up over the bunch. It is that easy.
Every time I use "The Sinch" I love the simplicity and the fact that it is always there when I need it.
