The iPhone 11 pro does not stay in place when mounted in landscape mode. Though, the phone does stay on the mount with not much hassle so that's good.
Perfect for a small car
I have an older VW GTI. There is no easy place for a phone holder of any kind. I already had a Scooch case. The Wingmount fits in the smallest of spaces. Finally, a solution to having maps available when driving my low tech car.
Works great! Put on face of dash and mount does not move with phone on it when going over bumps.
This thing works great and does not clutter up my dash.
