Custom Accessories 71183 3" 360 Degree Blind Spot Mirror, (Twin Pack)

Update: 4/9/2019:Worked out well after adjustment of side view mirrors themselves. (Installed the 2-incher on driver's side, lower inner corner, and the 3-incher on the passenger side, lower outer corner--figured since the passenger mirror was further away, bigger would be better. My side view mirrors on a Volvo XC70 were big--on a car with smaller mirror, the 3-inch would be too big).At first the passenger side one did not work well--stickie mirror was too big and hard to see since the cars were tiny in the stickie until they were right next to me. Was thinking about removing. But then, I watched a video on correct side view mirror positioning--man, I was doing it wrong for all these 50 years of driving.The instructions said, to position driver's left side mirror, press face against side window and adjust until you only see the edge of the car--I was positioning the left side mirror this way, BUT with my face directly behind the steering wheel, and not moved left and pressed against the side window. For RHS, put face in center of car, aligned with console/rear view mirror, and position right side mirror until can only see the edge of the car. Thus, after adjustment, when sitting straight in driver's seating position, neither side view mirror shows the edge or side of the car--a very uncomfortable feeling--and this is why I had always made sure I could see the edge of my car in both mirrors previously--the wrong way.And this is where these stick on mirrors come into play--at rest, you can see the edge of the car in them, on either side, although not in the side view mirrors themselves. The idea is when a car disappears from your rear view mirror, it should start appearing in your side view mirror. And when adjusted this way, the cars behind you do so--they gradually disappear from the rear view mirror and start appearing in your side view mirror, with the stick on mirrors showing the entire fish-eye image of the approaching car. Cool--so after 50 years, I finally got it correct. Oy Vey.Note, as mentioned, I do have Blind Spot Monitor in my car but what was missing was seeing what vehicle is there, not just a light indicating that something is there. And these little stickies do that--giving me much more confidence--especially when the Blind Spot Monitor is not 100% all the time.I tested this positioning extensively during my last drive, almost got into a couple of dicey situations because I was focused on looking at the mirrors and not straight ahead. But I confirmed that this set up works well.>>>>Update: 02/23/2019Installed it on my right side view mirror and did a road trip. Had put it in the lower outer corner, a bit high, not to the edge. But it was unusable--blocked the normal view in the side view mirror and made cars in blind spot appear tiny in the stickie mirror until they were right next to me. Will have to remove it and put a two-incher--it is way too big, even when I have relatively big mirrors in an Volvo XC70.>>>I got the 2 inch for my left mirror, figured I'd get 3 incher for the right mirror--not need to be symmetrical. Note that I have blind spot camera monitor, so won't be 100% dependent upon these--I just want to be able to see what is actually in the blind spot when the light flashes on.I was surprised by how big it was over the 2-inch--1 inch diameter makes a big difference. I ended up attaching it to the RHS mirror's lower outside corner--but I attached it too high--should have gone to bottom edge--I could not remove it to retry--had used a hairdryer to warm the installation after the alcohol swab, and pressed it for 3-4 minutes--it is on solid.One of the pair had a rough raised spot on the plastic edge. The mirror seems to have some glue showing at the edges. But they were cheap. I got a 2 incher of same format 20 years ago--mirror's a bit clouded now, but still intact and stuck on--it was a quality piece--couldn't find the manufacturer anymore.

They turned out to be just too big for the average vehicle. This is morelike a mirror replacement. They were unusable on my vehicle and youreally dont get a sense of scale until you actually purchase them.I'm giving it 3 stars because the product is probably fine for people thathave gigantic mirrors...maybe a semi? The clarity seems good so that'snice.

Stick and work as expected

This product is designed for additional safety feature. The unit is suitable for any vehicle.

I realy liked these mirrors but they didn't last long. Within two weeks both fell off while driving down the road. The adhesive pads are still on my truck mirrors. It was the adhesion between the spot mirror and the adhesive pad that failed. I have used the 2 in mirrors for years on two other vehicles never having a problem. When I installed them it was over 60 deg, and I cleaned the mirror with window cleaner and then both my truck mirror and the back of the spot mirror with alcohol. Once everything was good and dry I installed the spot mirrors by holding pressure on them for minimum of 1 minute. The truck was not driven until the next day. I did my best to prevent an issue like this. Like I said I have used the smaller version of these mirrors in the past using the same installation methods and they have been on those vehicles for 8 years.

Adjustability at 360 degrees. Clear and no more blind spots

First of all, I am a staunch supporter of spot mirrors. As a motorcyclist and general road user, I've been in a few close calls when people haven't checked their blind spots. I believe that it is criminal that all cars don't come stock with spot mirrors. As far as this product, they are a good size for most applications. Perhaps a bit large for some drivers for the driver side of a small car. They are perfect for both sides of my wife's SUV and perfect size for the passenger side of my Subaru WRX. Though they take up a bit of mirror real estate on a small car's mirror, I use spot mirrors much more than the regular ones. Most round spot mirrors are flat. Some are slanted, as are these. The thing that makes these unique is the rotation adjustment. Most circular spot mirrors are 50% worthless. I have no need to look at myself or the side of my car. These can be rotated out, so to speak, to increase side coverage. Stick it on. Then, because you can still rotate it, you can fine tune the angle. For an SUV, they can be rotated out and down.

These are pretty much what I have been looking for. The black outer casing makes these very thick, in my opinion. I originally got the 2" blind spot mirrors and they def needed to be bigger. 3 inches is the ticket! I just wish these weren't so bulky. I'll probably get the 3" flat version - perfect for the minivan. Adhesive sticks very well and installed in seconds. Overall this is a great product and would buy again. These are perfect for trucks and SUVs.

Didn't realise these were for trucks. Too big for my car. It's still a reflective mirror though. Not sure what to do with them. My fault for not reading the description.
