I got this shade for my son’s room, and needed something not frilly that would work with his current decor and with any changes we make as he gets older - just simple - that would block out the sun. 
The shade came with some simple instructions, and it was a little tricky to get the shade to attach to the brackets because of how close the window frame is to the ceiling (basement room), but in the end I managed it! The shade works so easily, and blocks out almost all light. 
Very pleased with the result and would definitely recommend!
