1) Assembly instructions were confusing. The pictures do not clearly show which holes each screw needs to go into and they mislabelled a bunch of their screw kits. 
2) The grooves in the back part where the back panelling has to go in were misaligned on the left side. We had to basically carve out the grooves ourselves to make the back panelling fit. 
3) It's hard to open these without handles; we bought our own to add onto the doors to make it easier to use. 
4) The spaces between each shelf unit is not very big; we had to take one shelf out to have more space to fit our shoes. If most of your shoes are flats/sandals, low-top sneakers, you won't be able to fit 18 pairs of shoes in the cabinet without taking out shelves. 

Overall, the experience of assembling was frustrating and the display pictures are misleading.
