The assembly was a bit daunting on the first unit and took ages to assemble but by the third of the six bought, it had become much easier. I would advise anyone purchasing these to clean out completely the pre-drilled holes on the shelves - it will cause issues that are hard to resolve once they are being put together.
Now that they are done, they look great and the value could not be better.

Pros: Look much more expensive than they were.
Cons: Assembly is a little daunting.
