Review on 3-in-1 Car Phone Mount Holder with Powerful Suction Cup, Durable Sticky Gel Pad - Compatible with iPhone 13 Pro Max 12 11 X Samsung & Other Smartphones for Windshield, Dashboard, and Window by Mario Beckwith

Very robust and durable. I've had this installed in my car for several months (from very hot days to freezing cold days). It has never been dropped and holds my phone well (Samsung s8+). Bought this for a friend as he bought a few others that didn't take this bi-polar weather well (the suction was poor or he wasn't holding his heavy, bulky phone for long). He loves too! Came with some flat pieces of metal to stick behind the phone.
