I am a courier and I drive rather quickly weaving in and out of traffic and it is important for me to be able to see quickly everything around me so I can react just as quickly. A friend of mine had the Wink 6 panel plastic rearview mirror which I decided to use and it was at first hard to install and even after a good installation it would need to be reinstalled if it got left in the heat of the sun. I began to remember to take it down on hot days if I was leaving the car for very long but the mirror itself melted because it was plastic. I saw this mirror was easy to install on your own mirror so I decided to try it. It gives the same view as the Wink but is smaller and so every thing you see is smaller. But other than that it works great, easy to install and it is not plastic so it will not melt. I don't have to worry about the heat. And it looks better esthetically.
