This holder works great but the mount to attach it to bike is a little limited so I built my own that gives it more freedom of movement allowing vertical or horizontal position. I mounted it to the handlebar
Works perfectly for my phone!
There are a ton of phone holder out there...most have one or more major problems. This one is the only one I could find that was secure enough to use every ride. Amazingly, this held my Iphone 6 in a water resistant case secure, so secure that unless you release it, it will not come out. Having gone over a ton of rough surfaces, in a very stiff bike, this thing works better than any one I have seen or tried. Not sure how durable it is in the long term (lots of plastic), but so far it works great. A couple things to be aware of: 1. It attaches to your tube (mine is on the stem) via threaded plastic parts...seems secure, but over time it needs to be re-tightened. That is attached via a single screw to the holder..make very sure that is tight, as it is below the holder and cannot be seen when the phone is it place. Lastly, push fairly hard on the side bars to lock the phone in place. It is a simple, and very effect holder if you do that.
Be aware that on an iPhone, the leg on the bottom that keeps the phone from falling out is right over the earphone jack is, so if you plan on listening to music on your ride, choose another product. Otherwise a solid feeling mount
