I've install these on both a 09 Tacoma and a 04 F-150. Didn't have too much trouble adjusting them on the Tacoma. I did have a little trouble mounting them at the correct angle so that they were actually useful. After that they worked ok. Put them on the Ford and it mounted a little easier. But on my last trip I was having troubles adjusting it to the right angle. While trying to adjust it, it was like there was a dead spot in it. The view too high. Try to lower it a bit then it would go too low. It acted like it was sticking and then it would almost "click" to the next spot which was way too low. After trying time and time again to adjust it the mirror finally just fell out and cracked into pieces. It snapped back into place but it's now a mirrored spiderweb. So that was the icing on the cake. Going to go find something better. These looks nice but lesson learned. Don't buy on looks, buy on quality!
