 gift 
 High quality and good price. 
 I just received my shield and I love it when I'm driving on a day the sun is in my eye and I having a hard time seeing the road ahead. It dangerous when the driver ahead of you hit the brake to slow down because he or she can not see. 
 nice secure fit,just the right amount of tint. 
 Everything is what I was looking for or expected. The clear plastic clip acted as a beam focusing mirror and is slightly annoying. 
 Just as expected great quality 
 as described 
 keeps sun out of her eyes and keeps her standard visor out of my eyes.  Now I can see to my right without having to bend and look under her visor. 
 I like it only thing is to big the clip other than that I like it 
 Product was just as advertised and shipping was very quick. Bought it for my girlfriend and she loves it. 
 Great item, cuts sun glare extremely well. Stays in place 
 Great for those days the sun is so bright. Makes driving a lot easier and safer. 
 Very nice, Now I can see everything despte the sun 
 It works. I'm not a sun glass wearing person so this product has helped a lot. If your visor is fairly thicker than normal like the ones in my Tacoma, you might have some trouble with the fit. It still clips on in my truck but it seems the clip might break from being opened too far. 
 Bought this for my daughter who's learning to drive and is too short for the visor to help much when she's practicing in the evenings.  She has been very happy with it, being able to flip it down to get a clear view without the glare of the setting sun. 
 Not as dark as I had hoped, from the picture it appears quite dark, but in reality it's just a medium grey color 
 works great 
 Looks and works O.K. , although the clip that holds it onto the visor is very large. 
 I ordered this for the driver side visor in my small SUV, which has a high windshield and I am not very tall. It attaches very solidly, folds down and stays at various angles, and stays put when it is folded-up. The smoked tint is effective for sun glare, and the vision quality is very good. This item is everything it was advertised to be. I also like that it can be positioned anywhere on the visor, allowing it to stick out and extend the width of the main visor, if necessary, when in the upright position. 
 What I really needed was a visor extender for when you swing your visor to the side during sunrise/sunset. However all of the ones I could find on Amazon were essentially $15 for a piece of plastic and a large rubber band. So I thought I'd give this a try instead since it was half the price and the placement of the clip measured exactly the distance I needed.
The only issue I had was that the visor wasn't opaque enough for the setting sun on the side of my face during my commute home. I ended up having to tape it up to block out the sun. If you're actually using it as a drop down visor though it'll probably work for you.
