Love It!
Nice sturdy phone holder. Fits perfect for a BMW X3 & iPhone 17 Pro Max. Flawless install. Adjustable to accommodate different cases. Exactly what I was looking for. Worth the price!

Great cell phone mount, super easy to install!!!
This is an awesome cell phone holder for the car! I have a 2022 X3 and it works perfectly and is super sturdy. It was so easy to install and I love that the directions include a QR code you can scan and watch a video on installation making it even easier. Once you put your phone into the holder it stays put and is in the perfect location so you can see the screen without taking your eyes off the road. I definitely recommend this cell phone mount for your vehicle.

It fits with my BMW X3 2022. It also has a back pocket that offers storage behind the screen. I wish it had a magnetic holder but that has nothing to do with this product.
