Fit System C0400 Driver Passenger Side Stick-On Adjustable Blind Spot Mirrors – Pack of 2 (Packaging may vary)

The only downside that I see is that the view is quite small. So, it is good for parking or other safe situations but not so much helpful on the highways. The distant cars are barely visible.

Funcionan excelente muy buen producto

Have been using these for a few months now and these are best little mirrors out of 6-8 pairs or so that I've owned over the last 10 years. They were easy to stick on and are still on there (we'll see how they survive winter), but more importantly they are easy to aim and yet fairly hard to bump out of alignment by accident. I've had mirrors that don't adjust and they weren't great. I've also had those that you rotate to adjust and they work great until you have to clean the side mirror at which point it's next to impossible to avoid knocking them out of adjustment. With these you push into the right alignment (like your rear view mirror) and I haven't knock them yet. The clarity/visibility is also very good. Just make sure to properly clean the surface of the side mirror you'll be applying these to and press them on firmly for 30 seconds or so. I did that and drove through an unexpected (but minor) rainstorm maybe 30 minutes after applying them and didn't peel off.

Best domed mirrors I've used. They don't get surface damage as easily keeping them clear and maintaining good visibility. The extra adjustment is nice too

Happy so far

I only used one, so I have a back up incase it comes off. These fit perfectly on my very small mirrors. Obviously, I purchased them for additional safety when changing lanes, so far they meet all my needs. They are sticking fine and they match the mirror on the left side which is nice. They seem well made so I'm satisfied. I do think when you put a mirror on the right side, that is so tiny, it's more difficult to see than the one on the Left. I was unsure in the beginning, but I've gotten used to it. It does take a little getting used to.
