Looks good quality goods. "Samsung S8 +" through the original case, without installing the magnet, charges in different places of contact. (I do not think that the magnet as it will affect because it has a thickness of 3 sheets of paper.) I still did not put it on the car, because I'm waiting for a package with a radio and I want to put it all together. How I will do and will understand the speed of charge and other nuances, I will add a review.
