Pros: - Good overall view of behind and sides up to rear door glass end portion (needless to say coverage of blind spot up to back door of car.) - Easy can see back seat passenger, including ur kids in booster seat ( No additional mirror required.)

Cons: - May interfere visor to go up to windshield, depends on car's space. Since it is 12" mirror. - Mind width of ur existing mirror, since this is clip on mirror, may not fit on bulky mirror. However, it can accommodate beyond standard width mirror.

Overall Review: Excellent clip on mirror. Must have thing for any driver. can easily see whole back windshield plus end corner of rear door window glass in 4dr sedan. Of-course, if you set up to top edge of rear window, you can have good view of rear seat passengers and it helps when driving with kids in booster sear. Single mirror helps to see more behind and partially sides + in car rear seat.
