The suction cup holds very well though they will fall off the windshield every once in awhile. I think its happened twice now. The company added some adhesive to the suction cup. A little worrying if you end up re-applying the mount several times as the adhesive is sure to get dirty and useless and need to be cleaned off. I cleaned it off my first one and so far it hasnt shown problems.
The mount comes with two metal backing plates, one rectangle and one circle. Both are small enough to fit in my Moto E though the circle works best.
The mount doesnt seem to shake overly much and can be tightened down with the adjustment nut if it does. These are a very good value.
Jay: I have a couple of these magnet car mount and from experience I suggest just using the circle metal plate because it won't block your NFC (if applicable) as much as the rectangle one. Also, these metal plate will sometimes cause a close-case like effect if you have it enabled on your phone.
