No glue suction base uses a sticky membrane to attach to your dash or windshield.  The mounting base features a removable "sticky" adhesive that provides a strong mounting connection, yet is removable and reusable without leaving any sticky residue.  Swivels into landscape or portrait mode.  Though the suction pad feels sticky to the touch, it will leave no residue when removed.  If the base loses suction over time due to an accumulation of dust or dirt, lightly wash the base with liquid soap to recharge the suction power.

Also included is an adhesive dash disk for a more permanent solution.
