I recently purchased my home and needed something to shade the slider door.  I hate vertical blinds.  I found these and I love them. 
1. Easy to size to your needs
2. Easy to install 
3. High quality parts and fabric 
4. MUCH better than any other options 

They look great, keep enough light out without making the room so dark I have to turn on the lights, and look like I paid a lot more.  

One tip. Check your bracket placement prior to install to ensure there is a spot on the cross bar for the bracket to lock into. 

This completely covers my standard size slider door with room to spare. 

Also it arrived a day early so it only took 4 days to get it from the day I ordered. 

Very satisfied very happy.
