Spent plenty of time looking for specialty rear view mirror adhesives because my factory mirror fell off while the car was sitting in the sun/heat. Came across this product and decided I’ll give this a try. For the price, it can’t hurt and it’s not a permanent solution if i still decide on going back to the factory rear view mirror.Pros:Adjustability - very easy to adjust. There’s a knob you can loosen and tighten that gives you a detent to adjust the arm up and down holding the mirror. The mirror itself can be adjusted with one hand but it’s not weak where you can accidentally brush it with your hand and it’ll move out of position. So far, the mirror has held its position driving on hot sunny days and rough roads.Suction - the suction mount itself stays in place once set. There’s some sort of sticky adhesive that probably helps with the adhesion. Find your spot and lock it down. From outside of the windshield, I can see where the suction mounts to the glass creating a black circle. If the black circle gets smaller, it tells me it’s losing its suction. So far it has remained the same. I even have it mounted halfway onto the black sticker where the original rear view mirror mount was glued too. Just to add, the weather has been getting pretty hot and no changes as well. I always put a windshield sun visor up when I’m parked and I’ve bumped this mirror every time and it won’t budge.Clarity - the picture is very clear and the blue tint really helps cut down on headlight glare. Nowadays, plenty of drivers use bright LED lights that are aimed way too high or the folk who drive with their high beams on (why?). The blue tint helps especially if you have astigmatism. If it weren’t for my side mirrors, I wouldn’t know someone was actually driving behind me with their brights on.Cons: feels cheap - the mirror itself feels fine. But the plastic feels a bit hollow. I wouldn’t exactly call it robust. Then again, I wouldn’t want the mirror to be any heavier. It seems like they made it as light as they could. The only real cheap feeling part is the adjustment knob for the arm. It feels as if you could over tighten it and snap something with little force. Finger tight should be sufficient. If your mirror moves freely or out of position easily after locking everything down, return your unit.Blue tint - the tint is way too dark. During the day it’s fine, but if you were driving at night on low lighting roads, it would look pitch black. If someone were to drive behind you without their headlights on (another why?), you would not see them. If your reverse lights aren’t adequate or you’re running dark tint on your rear glass, it could be dangerous reversing. I have bright LED reverse lights and a light tint on my rear glass and it’s fine for me, but take that into consideration if you’re deciding on getting the blue tint or regular glass.Wide view? - product advertises as a wide view mirror. It sees the same amount of picture as my factory mirror. This could be depending on which vehicle you drive.Overall, I think the pros outweighs the cons. I previously had purchased a “Broadway” style clip on wide mirror with blue tint that I will attach to this mirror. It’s not as dark and has a wider picture. Take note of one of the pics posted- the truck circled in red on both mirrors. One is lighter than the other to give you a darkness comparison. For now, I’m just running it as is and it’s been holding fine and the dark blue tint is getting less bothersome to me. I will update this review when I attach the wide mirror and let y’all know how it holds up. I like the OEM+ look if it wasn’t for the suction cup mount. Great buy and would recommend!
