Great easy to install mount
Great mount! Shakes a little on the highway but that’s expected. Works perfect for my iPhone 17 Pro Max and the mictuning switch panel.

Ho
If there was more room it would work great but your near your leg is always in the way and you really can't use the drink holder so for 60 bucks I would have never have gotten it but for a shorter person I guess it would be okay or if there's more room in the console area

Perfect phone charger stand with mag safe charger
Color: Black, Set name: With Cable & Adapter
Works perfectly. I have had this for a month and as long as you have a magsafe case on your phone, the phone stays on and charges. At night if you place it on the charger in the landscape position it can work as a clock and/or outside temp. It is not flimsy. So many I saw required that you buy a magsafe charger to slip in the stand first, this one already has one so you just place your phone on the stand to charge. Worth the cost, would buy again.
