I really like this phone holder. It is adjustable to fit practically any cup holder, and locks in so it can't change sizes when bumped. You have to hold the button, and reduce size to remove from cup holder. This is especially convenient with pets along for the ride. The grips that hold the phone are also adjustable with a locking mechanism so that the phone doesn't vibrate or get bumped out. It opens and reduces to sizes that should fit virtually any phone. Overall I am really happy with this phone mount!
