On verticals it doesn't clamp tight enough and the weight of the phone moves the vents left and right.

However, the weight of the mount and my iPhone can turn the vents in my Honda

and I was not able to have the phone stay up horizontal or verticalThe problem was also the weight of the phone and any bumps I hit while driving the phone with drop off the mount

However, the air vents in my Toyota Prius are fairly loose and the weight of the WizGear pulls the vent down when I place my iPhone 6+ on it

My only small gripe is that the weight pulls the vent so air is directed downward

Once you put your phone on it, the weight drags this and the vent louvres down, causing the louvres to sag.

I did encounter an issue in a Ford Focus with vertical vents where the weight of the phone pulled the vents to the left or right, making it difficult to use the phone.

The only problem is that the weight of the phone causes it to fall down a

the weight of the phone pulls down the air vent and then your display is looking down and you can not see the phone properly

The weight of the phone holds the vents down but that doesn't matter because the swivel has plenty of adjustment.

then the ball rotor became loose & now the weight of my phone (i7) makes it fall south, too bad, great concept

On verticals it doesn't clamp tight enough and the weight of the phone moves the vents left and right.

Also the weight of the phone pulls the vents all the way down which means you can't adjust it to a good viewing angle

I took off a point because even though it does hold the phone, the weight of the phone still causes the holder to slump downward
