Don, good idea on your wheels.
Thanks! (Yep, I'm getting old!) You made me think of a significant OMISSION in my post!
I should have said, "RECTANGULAR CONVEX MIRRORS"! (NOT the round ones!)
I should have mentioned, I ALWAYS use the rectangular shaped convex mirrors (on cars or the bike). IMO they give a FAR BETTER RANGE OF VISION when compared to the round ones. They have more curve than the round ones and therefore cover a much broader range of vision. (I've tried both.) Also, they don't cover as much of the stock mirror.
Bet that is why a lot of folks who have tried convex stick-ons still look back. With the round ones, you'd still have to look back. IMHO, the round ones are better than nothing but the rectangular ones will show you a LOT more of what is behind and beside you.
For years, I've used ONLY the rectangular ones. When I get in the car or on the bike, I check the mirrors immediately, to make sure they are right - before I start 'em up.
***Of course everyone must be guided by their own judgement, individually.
However, in many years of use - with the rectangular convex mirrors properly applied and mirrors properly adjusted, I don't look back. (I did to begin with years ago.) If there is something there, one or both of the mirrors will reveal it. I mount 'em and adjust the mirrors in a position where I can trust 'em. Then, I don't need to look back. Looking back could get me killed. And, the few times I have looked back, I found nothing that the two mirrors (together) had not already revealed.
I APOLOGIZE, guys. I should have said "RECTANGULAR" to start with - there is a vast difference in the two shapes.
Further, with either type, if you still feel the need to look back, please do so. I make no attempt to change your mind. I'm just sharing my experience FWIW. But if you decide to try 'em, please seriously consider the rectangular stick-ons.
Thanks, Don
