I bought this dock after using a lot of different products that always fell off of the windshield and didn't stick very well. The suction cup on this mount is SUPER stable and stays exactly where you lock it in. I really like the NFC tag built into it as well. I'm not super "techy" and just by setting my phone in the cradle it automatically took me to download the app that it interacts with. The Dock n Drive app is free and lets me use everything on my phone much much easier while driving. BY FAR the best windshield/dash mount on the market.
