Compare STYLE-A with STYLE-B
Both models are magnetic car phone mounts, but the STYLE-A can be stuck anywhere in your car as you need and the STYLE-B can be mounted on the dashboard.
In my opinion, clip one is more stable than stick one, because even if the stickiness is strong, after a long use, it will weaken.
However, stick one is more convenient than clip one, because you can stick it anywhere you like.
There are two metal sheets in the package, one is round, and another is square.
If your phone is large and heavy, you should use the square one;
If your phone is small and light, the round one is ok.
Note: when you use wireless charging, you should take the metal sheet off the phone.
