I have been very happy with this one because it actually grabs the vent fins and locks on rather than pinching. It is not going to fall off. Probably a good idea to tighten it every once in a while. The only negative I have found is that it might be a bit bouncier than other mounts. But I haven't found that to be an impediment.

I'm also just sort of prejudiced against amounts that require you to glue things to your car dash. This one does not.
