If you've ever used a command strip product, the process is the same: super easy. An additional command strip is included in case you need to repeat. Be sure to hold it for 30 seconds and then wait a full 60 minutes before hanging the canvas, especially if it's heavy or you're applying to a more textured surface. My only complaint would be the lack of any alignment. If your screen frame isn't perfectly straight, or you're looking both ways and your mount isn't perfectly level, you'll need to pull the control rod and start over. I think you can always file your teeth. Overall I'm happy with the two I bought. I think they are 0.5 cm thick. They stick out about 0.25 inches for a frame thickness of 0.75 inches, but it's not very noticeable.
