Note: This is not a peel and stick mirror. There is a protective coating on the mirrored side that peels off. You must supply your own 2-sided tape or other material to attach it. That's why it gets four-stars instead of five.What I love: Peel off the protective film and the mirrored side is as shiny and clear as a regular glass mirror. This acrylic mirror is very lightweight and thin. I easily mounted it with Gorilla Glue strips to an outside window. I'm using it as a rear view mirror since my computer desk faces the window and my back is to the office door. It is so lightweight that it can go anywhere. Be sure to use quality tape when attaching. It probably shatters easily if it fell down or got dropped.Plan to stick this up with mirror tape in our pop-up camper trailer and it won't break on all those bumpy roads AND it's very light weight. Just don't clean it with any abrasives! Plastic. The image quality is very close to a regular glass mirror.I like the fast shipping service, everything was well packed and the round mirrors weren’t cracked.BigI like the concept of this but the item was shipped with scratches on it which was disappointing.Great item, great priceIt came scratched and all the corners look defective.There is no peel and stick on back
