Why are some car mounts under $10 while others cost $30?

Price tracks magnet strength, build materials, adjustability, and added features like vacuum suction bases or built-in wireless charging. The budget clamps and entry MagSafe pucks here cover the basics well, while pricier models add stronger suction, premium hinges, or charging. Higher review counts on the cheaper models suggest many drivers are satisfied with basic mounts, so spend up only for features you'll actually use.
