・ Features an auto-catch function for easy smartphone holding. ・ Holder can clamp smartphones with a width of approximately 6.5cm to 8.2cm with a single touch. ・ Suction cup type for flexible installation (gel for uneven surfaces and an auxiliary plate are included). I installed it once as a test. The suction cup's adhesive gel has been used. Please bid with this in mind. Please purchase with a certain degree of understanding.
