I installed them on my bookshelf and the bottom part broke within minutes of putting them on the shelves. One broke almost immediately and I thought it was a production accident, but within 15 minutes all 4 broke. They might work for very narrow shelves, but not anything more than an inch thick. Edit: The company is offering me money to remove my bad review, which I won't do because it's not fair and people should know the truth about products if they aren't good.
