The most feared thing when driving is the blind spot. This wide-view extended rearview mirror is designed to solve this problem. It adopts a double mirror design with one large and one small - the main mirror is a flat mirror that can truly reflect the road conditions behind; there is a small convex mirror next to it that can reflect the side blind spots. I especially like its adjustable bracket, which can be installed on basically any car model, and it can be done by yourself in a few minutes. After installation, it is very stable and will not shake when driving on the highway. It is much better than those cheap ones. After using it, I feel more at ease when changing lanes. I can see the cars coming from behind clearly, and I no longer have to worry about electric cars that suddenly appear. For people who drive frequently, this is definitely a magic weapon to improve driving safety.
