I'm very happy with our new CoulVue. I think I probably got one of the new units.
The only thing I would prefer would be maybe a longer arm, and a release mechanism to pull the ipad2 out without unclipping it. The problem is you really can't leave the ipad in the vehicle overnight, or you risk someone breaking your window to get to it (in a city, at least). So you're clipping it in and out every time you use it, which I worry will wear on both the ipad and the coulvue.
What I'd really love to see is a quick-release mechanism where the arm meets the ipad mount, so I can throw it in the glovebox/ or take it in inside with you.
The other thing I worry about is only a 90 day warranty, which feels pretty short. When I was installing it, it felt like maybe one of the two bolts was stripping, as I felt I kept turning it and it wasn't getting tighter. My issue is that now I'm faced with possibly returning a non-defective (or very minorly) defective unit when I don't want to, only to make sure I get it in within the 90 day window, or risk it causing problems in the future. It seems to work fine now, but I'm worried about the bolt stripping further...
