Amen to that. For every car I've owned since 1999 I buy one of these first thing. The one from my 1999 Integra is still in use by another friend who took it when I sold the car. Those things are immortal and nearly indestructible as long as you take care of them. I don't know any $6 sunshade that will last that long and look as good.
Let's not forget about effectiveness. You want your sunshade to block the sun, obviously, but what about the heat and UV rays? Just because it blocks the sun doesn't mean it blocks anything else. There is an incredible difference between the amount of heat the UVS100 blocks compared to any other sunshade. They are custom made to fit your windshield precisely and they leave very little space for any light or radiation to get through.
The really nice thing about that for me is that I can put the sunshade up when I'm parked in a parking garage and it absolutely eliminates the window shoppers. Without any light coming in through the windshield, the tint on my windows is impossible to see into. That is only 20% tint too, so it isn't like you have to have limo tint to accomplish that. I like having it up at night for the same reason. It just keeps people from seeing into your car.
Picture time.
Here is an example of the inability to window shop.
Sorry about this one. I had used it to photoshop some different wheels I was looking at and I don't seem to have the original uploaded. It shows the amount of light blocked again though. I'm just really a fan of any sunshade that can give my interior privacy when it is up. Someone would stand out trying to look in there.
The UVS100 is ONLY worth it if you plan on keeping your car for a couple years. If you are the type who never registers the same car twice, then it is probably a little spendy. However, considering it is
only like $60 bucks, it really isn't that expensive. You can spend a lot more on less valuable things. And when you sell your car I would wager you could still sell your sunshade for $40 or $50 bucks on Ebay. I bought one on ebay for $35 that actually had some cracks in the seams and I still felt I got a bargain.
If that isn't a strong enough endorsement of a product, then I don't know what is.

Definitely look at getting one. It will be the best sunshade you ever purchase and you will love the difference it makes to the security and comfort of your vehicle.
