We ordered two blackout roller shades. The shades successfully block out the strong morning light and prevent glare our computer screens (our main reason of purchase).

It also wasn't too difficult to install, although the directions were confusing. They numbered the first step as "step 6", and halfway through is "step one". If you just ignore the numbering mistake and go from top to bottom/left to right, you'll be fine. Actually, the most difficult/time consuming part of the installation process was in setting the pull up height to where I wanted (especially in matching two shades next to each other). 

All in all, the shades serve their purpose at a reasonable price.
