1. The difference between the classic suction cup and the super suction cup: the super suction cup features a layer of black polymer soft sealing material that automatically fills gaps up to 1mm on uneven surfaces, providing a secure lock and reliable hold without the risk of falling off. 2. Advantages: installs in 5 seconds, provides long-lasting adhesion for up to 8 years, resists humidity and water, and withstands temperature changes. Automatically conforms to minor surface irregularities within 1mm, offers 2-3 times stronger adhesion, and features a unique 60-degree locking design. 3. Can be cleaned with tap water and reused multiple times. 4. No drilling, nailing, or gluing required; waterproof and moisture-resistant with strong adhesion. Can be removed and reinstalled repeatedly, suitable for use in humid environments. 5. Instantly locks in vacuum seal for long-term use. Factory reset (“one-turn recovery”) can be performed by gently turning until a click is heard, restoring full suction strength like new. Simply press, turn, and lock to reset the vacuum seal.
