B&Z Solutions Original 4-Pack Car Window Sun Shades Bundle-Universal Fit All Vehicles-Easy and Effective Way to Block Sun Glare, Harmful Heat, and UV Rays from Children or Pets-Black Static Cling Film

Unlike most of the other reviews I found for this product, I did NOT receive any discount or free product or anything else for this review. That being said, these did what they advertised and have worked great so far. They go on easily and haven't fallen off or moved. They allow the window to go up and down with them on. They reduce the amount sunlight coming through the window without completely blocking the view. I've seen other reviews critical about air bubbles and it's true that it's hard to completely get rid of air bubbles when you're putting these on (and in fact I didn't get rid of them all). However, the presence of air bubbles didn't affect the ability of the product to 1. stick to the window 2. work effectively to block the sunlight or 3. prevent the product from still sticking to the window with window rolling up and down. So in my opinion, unless you're super particular about air bubbles, no big deal. They seemed to keep my kids comfortable (a nearly 4 year old and an 8 month old) for the 12-14 hour drive to and from the Outer Banks, NC so for the price I think they're great.

These are worth the cost, -- but not much more. They are helpful and as advertised. However, they are challenging to apply and very hard to store when not needed. Imagine how plastic food wrapping clings to itself -- and you will understand. They come mounted on cardboard sheets to which they can be reattached -- but with great difficulty. I used these to replace the "window blind" type of roll down shade -- and I prefer the roll-down shades (which also has drawbacks). I am not aware of a better solution on the market -- perhaps some day!

I'm not a paid reviewer, I'm a mom with 2 babies. I love these sun shades. They are pretty easy to put on, and do a great job blocking bright sun. I drive a mini van and the kids are in the captain seats. I deducted one star because they could be much bigger. I'm considering buying a second set to fully cover my windows. I've positioned them the best I can to get max coverage (this took a few tries). I love that the windows can still be rolled down. I always accidentally tried to roll down my windows with my previous bulky set, inevitably leading to them popping off... So this feature is great.

You can cut these to the shape of your window which is excellent for that awkward little triangle window that the sunlight usually comes through and blinds your child from. My back windows are already tinted but that wasn’t enough for my baby, so these were super helpful. I only put them on one side since my daughter’s car seat is behind the drivers seat. The main window took about 1 1/2 of the sheets to cover everything, which was fine by me since we only put it on the one side. I had enough leftover for that awkward triangle window but I wouldn’t have had enough to do the other side of the car. If you’re looking to cover all the windows in the back, you’ll likely need two packs. But they were super easy to install - they unstuck from the window nicely so I could move them where I needed to and they still stuck when I put them back on. You can also roll the window down with these which I love, since some other ones are too thick to do so. I would absolutely buy them again.

These things are terrible the are hard to put on and does not stay stuck to the window especially if its hot. I got them on after forever fighting with them and many bubbles. I left work to go to my car to leave and on a hot day they fall off and like shriveled up I had to undo it and try to stick it back but that didn’t work at all......hey are also way too small the need to atleast cover most of the window I had to try and figure out where the sun would be hitting my son’s face and stick it there because these didn’t cover most anything......

Worked great for a day until it fell right off the window. Window was cleaned, all air bubbles were squeezed out, and all corners were flat against the glass and it still fell off under its own weight. I don't even live in a hot climate, either (average days have been in the 70's). Bought this after reading all the glowing reviews, so I don't know if they changed things or not, but these just refuse to stay stuck!When it is stuck on, it works perfectly. Just too bad it doesn't stay on. Wouldn't recommend, sadly.*** EDIT 5/28/15 ***Despite cleaning the window and applying, I was still having issues with the product eventually falling off. I decided to apply with a little soapy water, which did make getting the air bubbles out a lot easier. A week later, and the screen is still holding strong! I don't know if it's the curved glass, or the tint I had, but without applying with a little bit of water, it wouldn't stick. Changed my review from a one star to five.So in conclusion, if you're having problems with it sticking to your window, wipe down the stick-side with a bit of water with a drop of dish soap and apply. Rub out all the air bubbles and you'll be good to go!

Bought these to replace a pair from the brand Sunnies. Sunnies brand worked great, blocked sun, but could still see side mirror for traffic. These....vision is totally blurry. Blocks the sun, so useful there but if you hoped to see through the window, forget about it.

These are the best shades I have used so far on my SUV. Stays on nicely (tested for over a few months now), easy to apply and can be removed and reapplied again . I have done this a few times and moved it across windows. Also thin enough membrane and does not interfere with the power windows assembly. Effectively blocks light and does not block view. My kids are thankful for these especially on long drives. The only thing I wish they had was different sizes as they are too small for the back windows of my SUV. Super Happy though.
