After I read this product, there are some opinions I have about this BC 30 WB. that is :
Pros:
This product works like a rearview mirror, it's just so much more sophisticated and cooler than the rearview mirror. Sometimes we do not pay much attention to our view from the back. Because if using the rearview distance we are limited sight. This is a cool innovation in my opinion. Because in addition to the many advantages that we can, we will also be more vigilant because our visibility is much clearer.
Cons:
This product is good, it's just because the supporting features are sold separately we have to incur additional costs.
