To do that I had to mount my phone on the handlebars but wasn't sure about doing that because I was worried about the phone falling off the mount while I'm going down the highway

but it says it can be used for it but the part that you tighten the back for the angel ball that collar fell apart and my phone fell i was going about 21mph lucky my phone fell onto my left

I have no concerns with phone falling or slipping while riding!

I don't feel paranoid about my phone falling out of this mount

this holder instills confidence and I no longer even think of my phone falling when I go for vigorous rides

It works well and I had no worries about my phone falling.

Holds well no vibration or fear of phone falling, although a major flaw is as stated by others the rubber mounting covers the actual window switch and back buttons

This mount works as it is described

works as it should fits perfectly would recommend.

Works as

This broke as we were putting it on our bike

Except the ball in the ball-joint which allows the case mechanism to sit, sometimes splits apart as if not glued/assembled properly.

As you would expect, I was a little worried my phone would fall out as I enjoy cross country and some single track mountain biking, but there was no need for concern.

I wondered if the iphone would shift at all during riding, but no worries as it maintained its position throughout my first ride
