Suction Cup Blind Spot Mirror, Ampper HD Glass Frameless Removable Convex Wide Angle Rear View Mirror (Fan Shape, Pack of 2)

Can fall off of use heated wing mirrors or when very cold. But generally stay on pretty good

Rubbish. The suction ones easily come off despite how hard I tried to attach it and I've already lost one of the mirrors after a few months

Both of these fell off my wing mirror within 10 mins of starting driving. Absolutely pointless - I returned it.

It may just be me but I couldn’t get these to stay on my wing mirrors

The suction hold works better than expected, it’s been a month and they are still holding on strong

I love these so much! I got the suction cup ones as I wasn’t sure about the ability to remove them and I couldn’t do anything permeant to my car. This was absolutely perfect and makes me feel so much safer when driving by increasing visibility. The suction works a lot better than I was expecting. One fell off after ~3 months, but I didn’t hesitate ordering it again to replace the one. It’s so worth the money.

Used these on a road trip through windy and a rain storm and they didn’t budge!

It sticks well...until...if there's a temperature change. Frist time it fell off on a parking space this winter when the temperature dropped. That time I could recover the mirror. Today it fell off when it got warmer. Whilst driving, so I'm not seeing that thing again. Because of this it probably also will fall off when you have a heated mirror. It's totally useless.

I drive a Jeep Wrangler, and blind spots have always been a problem. These convex, wide-angle blind spot mirrors solve the problem. One suggestion - I found that car washes knocked them out of alignment every time, so I put a couple of drops of Loctite Blue on the ball joints and positioned them where I want them. Problem solved.
