I received this stand today. 
1. There was no screwdriver inside the box, I contacted support, to ask type and size of the screwdriver to buy, and they said they don't know and that I have to go to the shops to show the screw to buy it.

2. Instruction for assembly is so complicated.
3. Quality of the product is questionable and very heavy
I don't recommend this product, especially from Wayfair which they did not support.
