Pretty good overall. It's hard to screw all the way in and it would be great if the screwing mechanism had lugs or something else to put your fingers on to make it a little easier. But it sits pretty well in the cup holder of my F150 (2018 model). It doesn't wobble as much as I thought it would, and it's stable on some of Louisiana's fairly rough roads. Turning the mount upside down will help create a sort of quick release mechanism for your phone. It also kept my iPad mini safe on the road for about 7 hours (used it to launch Waze separately from my console screen). It was reliable too. The only thing that bothered me was that it's bloody hard to get into the cup holder and it could easily be constructed by simply redesigning it. Hence the 4 stars, but quite good for durability and stability.
