I just hit an expansion joint, the grip wasn't tight enough and the phone came out. I just saw something falling by the time I looked down and there it went into the morning rush hour traffic behind me.
The one you see in this picture is actually a RAM mount as well that works great, but it wouldn't fit the Note 2 with a waterproof case so I got that one to try. The only thing to consider is you need a thin plastic\rubber case so the plastic posts on the mount and the plastic housing of your phone don't grind each other down.
