That's great feedback, thank you! Glad to hear the setup is working well for you :thumb:
That is a valid concern - I also wouldn't want the phone to block the vent of my view of the road (which I think is a major shortfall of the Pro Clip concept).
I tinkered a lot with the design to get the mounting surface to where I think is best for most folks. For ~6' person, with the phone in a portrait mode, the vent is completely unobscured, and the top of the phone sticks slightly above the hood. It might block something that is a few feet to the right/front of the hood, but in practice I don't even notice it - it is less of an obstruction that the A-pillars. If you put the phone into landscape orientation, then nothing gets obstructed:
Also keep in mind that there is some flexibility in where you locate the phone on the mounting bracket - you can bias it up/down and left/right a little to best suit you. And the RAM holder option gives you even more flexibility.
Sorry for the threadjack!
