Review on BL Super Wide Angle Rear View Mirror - Universal Car Interior Mirror For Trucks, SUVs, And More - 300Mm X 85Mm X 33Mm - Curved Design - Pack Of 1 by Abdulkarim Sugge

OK, these type of mirrors are NOT for everyone. They also render useless dimming mirrors, but provide three distinct advantages:1) Position it so the left side of the mirror shows a direct view out the back (not your face), and when you do so, the middle to right side of the mirror provides a sweeping view from rear window across to your right side blind spot.2) This mirror allows you to keep your eyes forward by eliminating what is often multiple head turns to verify no one is in your blind spot.3) If you suffer from limitations turning your head as a result of anything from stiffness to cervical fusion, this mirror is very helpful, as you do not have to turn your head as many degrees, or as frequently.4) It makes any right turn with multiple lanes safer because you can monitor cars off to your right/in your blind spot. Essentially, it provides an alternative to modern blind spot sensors (on the right side.).DISCLAIMER: This mirror is not a replacement for driving carefully. Monitor traffic and the position of other vehicles around you, and use this mirror to add confidence as you drive, not replace being safe and responsible. It also does not serve to monitor your left side. I tried it, and when turned further to try this, you see yourself at all times, and the view out both sides of your blind spots is not adequate to make it worth it. So use it as I recommend, or don't buy it.
