Does exactly what I needed for cheap, keeps leaves off and the sun out, thats all. Dust and water get in but what do you expect for the price.

I really like these curtains and the price can't be beat! We have an east facing panoramic window and used to get FULL, BLINDING sun in our bedroom in the morning. We put up these curtains and they really help darken the room to something much more manageable. These are not "vegas hotel-style" blackout curtains where ablsolutely no light comes in, but they cut the light down to about 20% from full sun. This is good for us because we can still tell when its daylight outside without the blinding light.

Does a great job of not only protecting from the flies but the sun too.  Good choice for the price.

These are great for the price and they really do block the sunlight 100%...well, the navy blue ones do, anyway, as those are the ones I have purchased. I would recommend them if you're looking for a reasonably priced & machine washable set.  They are pretty lightweight as well. One thing to note: Deduct a few inches in width because the width shown is the panel when laid flat, which they obviously do not do when attached to the rod (due to grommets).  So, you need to count on the width of each panel covering about 5-6 inches less than the measurements. I ended up needing to order two sets because I needed a minimum width of 99" and one set was not enough.

This is the second time I've bought one of these. The other lasted 12 years. Great for the price. It empties my above ground pool cover quickly without too much hassle. Great price considering how long it lasts.

Great Deal!  It keeps all the dirt and leaves off but it isn't waterproof.  Works fine for me

Very helpful in  the sun and also protects the lens. Use it frequently. A little hard to store in the camera case at times

These curtains are great for the price! We have smaller windows (width wise) and they are perfect. Also keep light out well.

For the price these do a great job at blocking out light. They of course aren't 100% sound proof, but they help keep my room cool and dark.

Very affordable way to block out sun.  Does a better job than blackout curtains for a fraction of the cost.  I am sleeping later and no longer waking up to a bright room at 6am.

Fits well and the brim helps keep the sun at bay. Would buy again.

Awesome for the price, fits and works well for bicycles and motorcycles. Has stayed waterproof for over a year. Never had a problem with it even at VERY high speeds and in direct contact with the wind

Perfect for the job of blocking out the sunlight. Cheap, easy to install. I would buy again when moving house & needing a temporary solution.

I purchased this cover to cover my pool filter, pump, and piping to protect it from the UV's of the Arizona sun. It's worked great ! It's easy to remove when I need to get to my pool equipment. It's lasted a year and is now showing some signs of cracking in some places so I'm ordering a replacement. $30 a year to protect thousands of dollars in equipment is well worth it.

Works great to shield the iPad mini from direct sunlight and from some dust.  My husband uses the iPad to score my son's baseball games for the team using an app.  The sun was a huge problem as he couldn't see what he was doing.  No more.  It is a bit big, but it does the trick!

This is a great sun blocker. The only negative is you can't roll down the windows while using the cling. Great value for the price.

This stretches out nicely, you will need some solid supports at the ends to keep it tight.  The dimensions seem to be pretty close the the stated 20x13 at the corners, so it will be slightly narrower on the sides.  This is great though, just what I needed.  The material is nylon (not canvas), so it is not waterproof at all.  But it does block 50 or 75% of the heat from the direct sun.
