Love the look, color and concept, pretty sturdy once you build it out, pretty easy and innovative since it’s the same designs stacked throughout.
Only problem is that unless the books have a certain volume then they’re not gonna stick into the corner and fall out. So either 2 or 3 books or the entire section needs to be filled for it to not come out while rotating wish they had a divider or a spring or something to hold em in place.
P.S. You need to load em evenly otherwise while spinning they get stuck and hard to rotate and start creaking.
