Set and forget:
Better image quality:
Limiting vibrations: vibrations can introduce blur which can ruin a video, even one recorded by an otherwise decent dashcam. Suction mounts tend to introduce shakiness or blur in recorded videos. It is inherent to their design, combining multiple parts together, often including a swivel ball and other elements that need to be manually tightened. All these factors contribute to lessen the rigidity of the mount. Adhesive mounts’ strength lies in their simplicity. The fewer moving parts, the tighter it can hold onto your dashcam. The typical mounts found on tubular BlackVue models are made of a single block holding the dashcam tightly in place.
Limiting reflections: keeping the dashcam closer to the windshield, thus reducing reflections.
