Hoping to have a car mount that was good for my use, I bought this one. And it's exceptionally strong, as many people already mentioned. I have a large Mate 10 pro, and on the silicone casing I attached the magnet plate.Two things that makes me remove a star (4 stars = I like it). The main reason being the adhesive on the back of the magnet plate. It hasn't entirely dropped off yet, however it's not long until the entire plate loosens. I don't know if it has anything to do with I attached it onto my silicone casing. It has lasted for 5 months, so actually not much to complain about.The other thing is also regarding some adhesive. The adhesive keeping the rubber in place, in the clamp - that sticks to the place to what you attach it to, has fallen off. It might be due to the magnet is really strong, and when I attempt to disconnect my phone from the magnet, I often twist and pull firmly on the mount. I had hoped the rubber parts not to fall off - as it sticks much worse at the moment.Note that the product has an exceptionally strong clamp to be so small - same goes for the magnet.But, again - 5 months for a cheap and well-made product ain't bad. Had it lasted for a few more months with my daily use (I drive a lot every day - and leaving my car often due to work) I would rate it 5/5.
