It’s too bad that the previous reviewer had such a negative experience. These work great for us! Maybe the clean windows on our new mini-van was a factor in successful installation?

Pros:

1) Setup was super quick. I was even able to peel and reapply in order to reposition/straighten the shade. The shades have never fallen off or started peeling at the edges, though we’ve only had them up maybe 4+ months.

2) Fabulous at keeping out sunlight, better than the roller shades that suction to the windows because it actually shades or dims the light rather than diffusing the brightness through tiny holes like the suction kind.

3) Since they’re static clings, we can put up 2 shades side-by-side in our mini-van and not have any gaps like we had when we had 2 suction roller shades next to each other.

4) We can actually roll down the window with these on, without wrinkling the shade (or worrying about suction cups popping off. Btw, one of our suction shades won’t even stick to the window anymore). But we don’t really roll down those windows, anyway, so I can’t speak to its durability after frequent opening/closing.

Cons:

1) Can only think of one; as it is quite effective in keeping out light, it can be a bit dark to see out of, particularly at night, (or on gray, rainy days) and with a mini-van, I need to be extra careful about checking my blindspot. (Thus, 4 stars).

** EDIT/UPDATE **

After such a great experience with the first set, we purchased another set back in January. However, they didn’t seem to have as much “cling”, and didn’t last 12 hours before they fell right off.

As suspected, it turns out that the cold Chicago weather was the culprit! After waiting for the weather to warm up, I’m happy to report success! My husband cleaned the windows (just as a precaution), and was able to re-install the shades despite the fact that they were practically crumpled on the floor of our mini-van for a number of weeks before we rolled them up again to store for the remainder of the winter.

LESSON: Don’t install these in the dead of Chicago winter! Btw, we’ve never had any problems with the first set, even throughout the winter (they were installed in Aug/Sept). This second set is looking pretty good so far (it’s been about a month).

** Update #2 **

Sep 2007: Since installing our first set 2 years ago, our 2nd set last summer, and our 3rd set a couple months ago (with the arrival of #3), we have not touched the shades since they went up and they are still working great. Perhaps a couple tiny bubbles here and there, but haven’t had to do anything! (Still don’t roll down the windows). If anything changes, I’ll update, but they seem to be going strong.

Even though I have tinted windows, that late afternoon and early morning sun was beaming straight into my sons eyes. These are perfect. I followed the directions, kept the other reviewers comments in mind and even though there are a few bubbles, I really don’t care.

The only tiny complaint I have is that NO WHERE on AMAZON in the product description does it say you are not supposed to roll your windows down; as it states in the product instructions. However, since they are pretty inexpensive if they come off I can buy new ones or just get limo tint on my SUV.

The shade was not the easiest to apply without lots of bubbles, but since it can be reapplied endlessly, it works fine if you have lots of time and patience. Also, since it is a generic rectangular shape, rather than being fitted for the shape of the car window, it didn’t block the sun in certain areas. But, other than that, it did the trick.
