Pretty easy to install, took me about 15 min to put both of them up. I definitely used the screws for the mounting bracket instead of the double sided tape for more stability. The only complaint I have is the chain feels cheap being made out of plastic so we will see how long that last but replacing it with a metal one should be cheap and very easy to do if it does brake. Basically for $60 for both together this is your best choice and honestly I do really like them.

First of all this was our second attempt. My wife reordered due to my measurement mistakes. With that said, the product is surprisingly good. It feels and looks quality made. The install was 20 minutes to install to both patio doors. We like the how versatile it is with the grey colored shade. The blind allows certain amount of sun light to go through the windows. We are very happy with the purchase.

I like these: they look nice, they provide some privacy (office double doors with large glass panes) and they can be completely rolled up and out of the way when you want your doorway to really look open. The mechanism to roll up/down is nice and smooth (at least when they are new). Also, there are very few options to cover a 84" tall window.

Critical Points:
- DO NOT CUT THE CORD. The looped cord is almost as long as the fully extended blind, but you cannot cut the cord. If you do, you will need to repair it: you need the full cord length to fully extend/roll up the blind.
-UNDERSTAND THE SIZING: the widths in the listing are the widths of the roller assembly, the blinds are narrower. In my case, my windows were just under 21" and I purchased the 23.6" wide version. However, the blind material is only 22" wide. If I had known this, I probably would have purchased the 25.6" wide version, to block the views at the sides of the windows better.
- Don't drop the rod weight out of the blind when you take it out of the box; if you do, you will probably put the rod back into the material incorrectly. If you do this, the material is further away from the door/window (blocks less of the side view) and the blind will not roll up very well.
- The looped cord is on the right side of the blind, as you are facing the blind. This means that the cord hangs right next to/on top of the handle of the left-side door of a pair of double doors. Nothing you can really do about that because YOU CAN'T CUT THE CORD.

Other Details:
- These are not "blackout" and they do not provide total vision-blocking privacy. The material layer closest to the door is still about 1 inch away from the door, and the second layer is an inch or so away from the first layer, so they absolutely let light through and you can see around the edges or in "slits" up toward the ceiling or down toward the floor (depending on exactly how you align the two layers of material).
- The little plastic holder used to pull the cord straight and keep it from flopping around against the door when you open and close the door is functional but just a simple piece of clear plastic that, due to the orientation of the mounting hole, makes the cord do a 90deg twist from top to bottom (not so easy to describe, but at the blind mechanism/at the top, the loop is on a pulley perpendicular to the door, but the little holder at the bottom of the cord has a "pulley" which is "parallel" to the door). It annoys me and I don't like it, I'll have to come up with something else.

These are great

I did not know what to expect but I absolutely love this blind! I am not into anything that requires installation and this was super easy. I took the advice to not use the double-sided tape included and used the heavy duty double-sided tape purchased on Amazon. Best decision ever. I am ordering 2 more to complete the look. Very satisfied and happy customer.
