Please read the entire description if you are considering purchasing. I bought this at Yellow Hat intending to use it in my car, but it wasn't compatible with my smartphone, so I'd like to pass it on to someone who can use it. Please note that it cannot be used with smartphones that support wireless charging. There is one round metal plate and two square metal plates. However, I used one of the square plates, so the included accessories are one round metal plate, one square metal plate, and two transparent protective seals. The mounting base is also unused and included. Please refrain from purchasing if you are sensitive to items that have been previously owned. A stand that securely holds your smartphone with strong suction. - Model Name: AT-55 - Suction Power: Approximately 3 times stronger - Mounting Method: Compatible with air conditioning vents and adhesive mounting Feel free to ask any questions.
