Works great. A litle too large for me. I didn't realize there were two sizes and ended up with the larger size. Put them on the outside mirrors of my new KIA (which has pretty good sized mirrors). They really give you a good view of what is beside you even in your blind spot, but they don't leave much of the KIA mirror usable. Next time I would get the smaller size. Close but not quite The hot spot is a good quality product. There is no distortion in the mirror. It's just a little bit too small to be effective. If you could find something about an inch wider and a 1/2" higher it would work much better. I installed the hot spot on a mid-sized crossover. Eliminates Blind Spots Works as advertised. Would have been just as happy with the smaller version, but luckily I have big mirrors so the larger ones are OK too. Not worth it or useful I bought the 1.25" x 2.25" stick-on wedges. I placed them on the inside bottom edge of both driver and passenger side windows. No problems with installing and they seem to stick well. After trying them for a week, the bottom line is they are too small to be useful but just large enough to be distracting. They actually made it harder to drive safely. Works pretty good for intended purpose I had one virtually identical to this from Brookstone many years ago. It was really convenient not having to lean into the side mirrow or looking over your shoulder to see if anyone was in my blind spot. I've been looking for similar size, but all I saw were either too big or round and took too much realestate on my side mirror...until I saw this product from CIPA. The "mirrow" is not real glass, but a polished foil. This results in slightly blurred view, but given that the purpose is to see your blind spot it doesn't have to be perfectly clear especially things already look smaller anyway.
The mirror comes with a double-sided form tape. Be sure you play with the positioning as it's not movable once you put it on. I suggest you tape it on with a scotch tape to make sure it the position is not distracting from your normal driving position (hint, avoid the part of your side mirror that you look at naturally)
There's nothing to complain especially at that price.
