Using this product is a breeze. If you want to use it as a phone stand, just place your phone on the magnetic hook in the back seat. To hold heavy objects, make sure the object doesn't exceed 5 kg and put it on the hook. When choosing a place to install it, pick a smooth surface like the windshield. As for maintenance, clean it with a soft cloth every once in a while. Avoid using sharp objects to scratch it, and keep it away from high - temperature areas to prevent the plastic from deforming.
