Review on CY Craft Floating Invisible Bookshelf by Jennifer Costa

I'm tired of things falling in my shower. I would have liked a little more storage space. So I got 6 packs because they look like decent little shelves and I think I could find a use for the other 5. I didn't have a spirit level or ruler and didn't want to risk just drilling into the wall in case there's a pipe in the way and you're worried about trying to hit the stud and all that. So I measured my height at 16 inches from the ceiling, made marks in a couple of places to make sure it was level. I then placed some clear gorilla silicone on the back of the shelf, used a shower curtain swivel rod to hold the shelf to the wall, and applied masking tape to keep it in place. I waited a few hours for it to dry and voila! The shelf has held up very well so far. But I've used this gorilla silicone before and I have no doubt that it will last.
