I have one and really liked it until today.....when it broke.
The plastic part that fits around the pin, by the O ring
just broke and kind of disintegrated. I don't remember
bumping it or anything. I just looked down and it was
broken....I have no receipt.
I took all of the plastic off the back and I am going
to figure out a way to attach it to my dashboard,
so it won't be a total loss. I wanted a car holder
anyway.
