I have used a lot. But it is the best support I found, well suited to all the air vents for my Nexus 5 provided with its case. Implementation and instant removal. Discreet, bulky and not very sturdy, fits in your pocket easily. Firmly holds my smartphone. More vibration. Easy for touch in gps for example. Moreover, it is the least expensive compared to other identical. In short, I recommend it, you will not regret it.
