This device goes into the totally Cool, and VERY useful device category.
I've bought and given away at least five or six. I have one in each vehicle and it is used EVERY DAY. I bought two more today, one for one son, and another for the next friend or relative that sees it and wants one. Great for stocking stuffers, too.
You slip a provided metal plate into the back-side of your phone's case. Put the case back on. Slide the large ( or small) grippers onto your vehicle's vent slots...and just hold your phone up to the device.
Viola, your phone is held magnetically onto the front of your vent. To remove, you simply tilt the phone sideways. Don't pull straight away, because you will pull the device right off of the vent finds.
One of the very useful things that I have ever purchased. Inexpensive, too. richg99
