The packet came quite fast and it looked big.
The product itself was acceptable for the price, especially my price was further reduced due to openned box.
The assemble work was easy, but needs time and organisation. I got to sort out the big bag of the hard wares since they had been put all together in one bag.
My suggestion: 
- modify the picture in the step 1 to make sure that the right side is joined together. I did wrong because of following exactly the picture.
- I would avoid the styropor as it causes a big mess in my home, it takes me lot of time to remove the sticky particles.
I am satisfied in general with the product accept the mentioned issues, that is why 4 and not 5 stars.
