Review on CIPA 49404 Corner Wedge Stick by Luis Jacob

Totally agree with Eugene Kim's 2010 review. half the size, it offers a better view of the blind spot (bigger image with less distortion) than the 2x2 model I used before. A 2x2 model that lasted 2 winters on me before I took it down to use this one. Be careful when sticking the mirror. Be sure to wipe the mirror with a good glass cleaner. The 90 degree angle should be pointing toward the center of your mirror. I screwed it up on the first try, took it off with effort, put it back on, and it's still holding up very well. Everyone should be using some kind of blind spot viewer!
