I really dig the style and sturdiness of these corner shelves. I wanted something that didn't require screws as well. The "hanging" procedure was a little more involved than I anticipated - as it took a few days to cure - but it's working great now! I was also surprised at how well the tape used to support the shelves while the glue cures does a fantastic job (I was worried it would lose its grip and the shelves would fall).

Overall - if you're looking for discreet, sturdy, corner shelves for a fully square corner (as mentioned by other reviewers) - these are an excellent and cost effective solution.
