Reusable & Residue-Free: Unlike single-sided suction cups permanently attached to phone cases, this one features 28 suction cups per side (no adhesive), ensuring a reusable and residue-free connection. You wont have to worry about sticky residue transferring from your phone to your fingers. Easily remove and reposition between car windshields, gym equipment, and windows. Stress-Relieving Popping Sound: Enjoy a satisfying popping sound when connecting and separating it doubles as stress relief! Use it as a desktop phone stand to shoot dance tutorials, makeup sessions, cooking demonstrations, or outdoor video calls with professional stability, even with bulky phone cases. Note: Does not adhere to leather, fabric, matte, textured/unsmooth, or rough surfaces or phone cases. Waterproof & Durable: Made of waterproof and durable silicone material, it's perfect for steamy showers. When the suction weakens after long use, reactivate it by rinsing with water and pressing firmly. Washable silicone maintains grip strength through hundreds of uses, making it a cost-effective alternative to disposable adhesive mounts.
