Cute storage shelf.
Size: 12 cube
This is particle board, as expected for the price. Instructions were easy to follow. I assembled it alone but there was one step that would have been easier with 2 people. I have a better Allen wrench attachment than the one included and it saved my fingers a lot of pain. It's cute when assembled. The openings are 10.5x10.5x11 inches so 11x11x11 inch baskets don't fit but you can find 10.5 inch baskets that work. It's very sturdy and the way it's constructed, the shelves shouldn't ever droop. It's a good value for the money. It's perfect for my sewing room.

Smaller than expected.
Size: 8 cube
The directions were complicated with only image directions. One person can put this together. It took me about an hour. The item is smaller than I expected. The image is misleading. Definitely not waist high for an adult. More like thigh height. Guess I should have paid more attention to the measurements instead of the image. It looks nice when assembled. For the price I expected something taller.

Great for the price — OffiGo 8 Cube Organizer Bookcase, Modern Farmhouse
Size: 8 cube
I bought this for myself after reading about it online, and it's been pretty solid so far. It works as advertised for daily use and fits into our routine well. The build/quality feels good for the price, though I noticed a minor issue that you should be aware of.
