Convex Circle Mirrors (Blind Spot Mirrors)

New RFDer here.

Would people with experience buying, using, replacing / removing aftermarket convex circle mirrors (especially on sedans or hatchbacks) chime in here about things like whether they find them useful, which ones to get (or to avoid) and why, and other things that it's good to know about them? I'm thinking of putting them on a sedan's side mirrors, but don't want to cause damage, put them in a bad spot, etc. Also, it seems that there are ones that stick on to the mirror but stick out on a hinge, not just ones that are more like 'normal' stickers--are they better (at least in some circumstances)? I've tried researching them on Google (and here on the forums) and didn't learn much of anything--I may well have missed some obviously helpful website/guide/thread, so if there is one, please let me know.

Thanks in advance for your help!

Why different sizes? I'm glad that yours have lasted 8 years so far.

I bought sleek rectangular blind spot mirrors and broadway rear view mirrors for my BRZ (low coupe poor blindspot) and it was life changing. Don’t even turn my head to check as I trust the mirror combo 100%.

It's the first thing I buy with every new car.

This is the set I use:

It's survived a winter and several car washes. I didn't bother using the pivot base.

What's the best position to mount these? I'm thinking the top corner furthest from the car?

That's my guess, but I wouldn't know what to do for cars with more rounded side mirrors that don't have that corner.

I always put them on my cars. I just get the 2-inch~ish circles ones from CT. After sticking them on the mirrors they last forever (probably had them for over 10 years on my old Civic).

I put them in the outer-lower corners of each side mirror, so that I can also use them to check the lines and the curb when I am parking and stuff.

Ditto. I have been using these for 20+ years.

I have tried various spots on the side mirrors and found the lower outer corner works best. That is where I find they work well for parking to see the lines or curb, be it reversing into a stall or parallel parking, and I like having the upper part of the mirror free to see more of the lane next to me. With my latest vehicle I have a manufacturer installed angled mirror in a cutout in the upper corners so I cannot put them there in any case. This OEM angled cutout does not show the lower part of the vehicle so I still stick a convex mirror there as well.

I prefer the circular ones that you can adjust the angle slightly which I think I somewhere in between 2 and 3 inches diameter.

Over 4 vehicles I've only ever had one fall off. The adhesive from the pad cleans off very easily with something like the citrus based orangesolv or gum-off solvent if you want to re-position or try a different size. They're cheap so if you don't like where it is positioned, buy another one and try a different spot.

Has anyone used these mirrors on a car that doesn't really have outer corners on its mirrors--like a third-generation Rio?

If you position your side mirrors correctly, you can eliminate blind spots without having to buy these extra attachments.

You are way over thinking it...... hopefully you don't ask about real oil vs synthetic oil.
