Bests & Worsts Reviews from Amazon

So let's start with the bad, this thing does block your air vent making it virtually unusable, the range of motion can also be hampered by the air vent based on how sturdy the fins are held in place, i.e. If the fins move easily, so will this device which can affect the viewing angle. Now let's move onto the good. The ball swivel can be adjusted to increase/decrease tension for extra sturdiness if required, the fact that it uses a ball swivel gives you virtually limitless options for positioning your phone (depending on the phones size), the mechanism to realease/clamp down on the phone is very easy to use, the a/c keeps your phone cool for those long trips (if you live in cold climates and have the heat on consider turning that vent off if you can to avoid overheating your phone). I've had 0 issues with this holding my phone in place even when inverted. Both my wife and I have one (we purchased hers first and tested it for a week before I bought mine) we both have iPhone 7s and leave them in their cases.
