1. Maximize your field of view: With the improved 360-degree swivel and convex wide-angle design, you can see three lanes. The viewing angle is maximized, effectively eliminating blind spots and achieving the highest level of safety without affecting normal driving. 2. Stable Design: The ABS anti-collision shell protects the mirror surface, which is more durable than the dead-angle mirror without the shell, and does not need to be replaced frequently. The blind spot mirror is made with 3M weatherproof adhesive that can be used to install pressure sensitive tape so you don't have to worry about it coming off. 3. Surface design: The scientific curved surface mirror can be adjusted freely, effectively eliminating multiple blind spots. After installation, the mirror angle can still be adjusted up, down, left and right. 4. Easy to use: first wipe off the sticky parts on the rearview mirror of the vehicle, and then fix the rearview mirror with 3M glue. It can be used after adjusting the angle. 5. Multifunctional Safe Parking Assist Inspection Mirror: For safety reasons, it is ideal for all GM auto parts, every truck, every car, every SUV, every motorcycle and every mobile home. Even beginners can easily reverse and park without worry.
