This kit includes 4 pieces of 3.15" and 4 pieces of 0.91" adhesive pads, along with 4 adhesion promoters, making it a versatile choice for various applications.

The larger pads are perfect for securing GPS devices, phone holders, and tablet mounts, while the smaller ones are ideal for reattaching small devices like phone ring holders or dash cam mounts. Made with durable, heat-resistant 3M VHB GPH-160 adhesive, these pads can withstand temperatures up to 300°F (150°C), ensuring a secure hold even in extreme conditions.

Users have praised the strong adhesion of these pads, with many noting that they stay firmly in place for years when applied correctly. One reviewer mentioned using them to reattach a dash cam to their windshield without any issues. However, some users found the combination of sizes odd and wished for an intermediate size.

The included adhesion promoters are designed to enhance the initial bond strength but come with warnings about potential skin irritation and allergic reactions. While effective, some users prefer to avoid using them due to safety concerns.

Overall, the 3M VHB Round Double-Sided Adhesive Pads offer excellent performance and durability. Whether you're mounting a phone holder in your car or securing a soap dispenser in your shower, these pads provide a strong and long-lasting bond that you can rely on.
