Gulaki's truly universal phone mount

I love the fact that even with this mount made for bikes, I am able to use it for my baike or in the car. It's the only mount I use now. The mount is easy to set up just turn and tighten around the bike handle or for my second spot I tightend it around the missing ashtray and I have a nice secure place for my phone to sit. it doesn't fall out after bumps on the road and very easy to remove when needed. The mount adjusts easy to fit all of the phones we own and we all choose to get the biggest in the line that we like.  Was a little confused about the use of the rubber part but the mount works well without having to use that. I know its an extra support of some kind but with no instructions on how to use it I just tossed it because phone stays in place without it.
