I had a windshield mount for one car. But it wouldn’t work on my other car. Tried the vent mount, but it wasn’t stable and broke the vent. Bought this one and it works great. Very secure and easy to use. We never use our CD player anyway, so it works perfect for our needs. Now both cars has its own and both work great in each car. I personally won’t recommend the vent mount due to it breaking our vent.
