I liked the concept of the magnetic insert verses constantly wearing down the female plug port of the phone; however the Volta inserts don't always stay in place and could use a tighter,grommeted connection to avoid being pulled out with the cord when hanging in a vehicle mount. A stronger magnetic connection wouldn't hurt either. If the cord moves, the magnetic connection is lost and often the C- type connection goes missing. I had mine a week and it's gone due to this. It's far to expensive and timely to replace.
