so far impressed with the holder!
can hold phone upright with easy sliding in our action, very secure unless you go over high jumps in the car then in my pop out, otherwise there is a clip attachment that allows you to hold the phone securly in landscape mode, haven't tried the it in the car yet as i've only just opened it. definatly not compatable with brodit clips tho. has a wierd scare mount system that seems to work fine.
