Unfortunately, we weren’t able to install this inside the window frame like we originally planned because installation brackets were a little too large for the frame. This kit allows you to install in or outside of the window frame, so we did it outside and they look great! They block out the light and offer great privacy. They look better installed than I initially thought so I’m really pleased with them. They are relatively easy to install, but I highly recommend getting a system down and making sure you have a level. It took two of us to install these since our windows are large, but if you have smaller windows, you could definitely install yourself.
