First of all, the good news is that the magnet is very strong! BUT - a "plate" that sticks to any hard surface, cheap and flimsy! So the laws of physics make it unsafe for your phone. I'm an engineer, so let me explain: I removed the tape, wiped it with rubbing alcohol, and then used 2 strips of Command to stick it to my tile on the shower wall (so I could listen to music in the shower). Shower). Then I waited 2 days to make sure the command strips had time to stick. But when I first used it, the weight of my iPhone caused the cheap plastic "plate" to buckle, causing the weight to no longer be evenly distributed across the entire surface of the "plate" (simple laws of physics ), which led to pulling out of the case. Wall. Luckily my phone didn't break. Lesson learned. I will come back and look for the best design.
