I just bought the Kenu Airframe+. Havent tried it yet but it had great reviews and its very compact. A little pricey but we'll see.
Thanks I am going to try that one out. It seems perfect.I have 2 phones, iPhone 6S and Galaxy S7 Edge so I like this mount as it's one-handed and fits a range of devices securely. I have it upside down suctioned to the windshield, coming down on the left of the gauge cluster. I swear the suction cup on this is the stickiest thing I have ever encountered, so it's really secure.
