4/5 product with 2/5 instructions. Took 6 hours to build initially, then hated the configuration so took another 2 hours to take it apart and a final 2 hours to put it together in a better way. I recommend building all of the cubies first and plan how you want to stack them. And screw some of the cubies into the shelves so the entire thing is more stable. In the end my configuration is similar to the product pic and I'm pretty satisfied.
