I don't have a specific photo handy, but I bought the RAM system where the ball mounts to the steering stem. Then I got the shortest dogbone double socket and bought their X-grip holder for my iphone. No need to change mirrors and the view of your phone is pretty straight on with the speedo not obstructed.
However, it sticks up in the air so your phone isn't riding down at your speedo level. You can see it sticking up in this photo
It's dorky looking but it is easy to remove, just leaving that black ball fixed to your steering stem.
The X-Grip mount holds your phone pretty well. My phone didn't blow away or even move at high speeds on the freeway.
Obviously, this is just my opinion but:
1. Cleanliness (as it relates to the bike) - 2
2. Ease of installation - 5
3. Sturdiness - 5
4. Adjustability/Visibility - 5
