It's so cold in winter right now and I found this magsafe car phone mount that allows me to securely attach my phone while not blocking the vents for heat! There is a swivel that moves your phone away from the vent, allowing you to enjoy warm heat or cool AC, depending on the season. Additionally, it's probably not good to have heat blowing and warming up my expensive iPhone...I hate getting messages that says my phone is too hot to use. Also, it raises the phone higher up so that it is more eye level so you can keep your eyes on the road with minimized distractions. This Lisen phone mount seems pretty good and reasonably priced at $11.99 if you use this code for the extra discount: SB8DTNAE. This clips and grabs onto your inner car vent slots to ensure a tight grip. IMHO, these are the best types of mounts and have worked very well for me.
