I have not tried the vent mount

Charging speed is about what I see on my home Qi charger, which means it's not quite as fast as the mini-usb with the OEM wall charger

It holds the phone securely

I don't have to worry about getting the phone positioned just right in order for it to begin charging

I like how the unit rotates, allow you to use your phone as GPS

Essentially the various components that make up this mount are similar to other types and it was not difficult to fit together the pieces needed for the Pro Clip
