I bought this for my husband as I have an iPhone. He says it works great and that he would buy another one. He is actually considering buying one for his work desk now. It has always worked perfectly and he can charge while his case is on.
Stays mounted on like it should and I have the biggest phone on the market. Galaxy s21 ultra with a heavy duty case, just make sure u tighten up the bolts when you get it in the position u want.
