Review on LUCKUP 100% Blackout Waterproof Fabric Window Roller Shades Blind, Thermal Insulated,UV Protection,For Bedrooms,Living Room,Bathroom,The Office, Easy To Install 20" W X 79" L(Grey) by Kyle Omaha

Tried these to do a double patio door. Hung 2. First, there is no way to get these to be less than 2” apart. The pictures they advertise show them with practically no space between them. I could live with this.What i can not live with is the cheapness of the materials. The plastice chains are of the lowest quality. I have had to jimmy rig these things to keep from popping all the time.The fabric, although it does block light, is flimsy and wrinkles/creases very easily. And due to the cheapness of everything else, i have lots of creases from it being left on the ground crumpled up, because the whole thing decides to unroll due to cheap chain and guide locks.I ordered another brand on amazon. Spent more but well worth it. Metal chains, quality hardware, thicker shade material. So i love this type of shade, would be weary of this brand, unless its for a single window that u do not plan on using ever.
