Has anyone tried those stick on blind spot mirrors? Do they fall off?

 

"New" owner of 2012 250C so all of these posts are new to me - I have a Toyota Venza and after careful cleaning the mirrors, the blind spot add ons stayed put for a long time. Have since adjusted mirrors better and blind spot is minimal

 

I use those mirrors on my RX which has ZERO visibility to the rear and they have been on for at least 5 years. Just clean the mirror real good with something that will get grease and road film off.

 

Clean with windex, then alcohol, and then a dry rag. I'd recommend a wedge style, with circles it's harder to see where a car is at a quick glance, esp at night. Last ones I bought were Hypersonic, a good size for sedan mirrors
