These nightstands are sturdy and well made. The gold knobs are a little cheap looking, but you can always swap them out. 
I built them both by myself (while looking after a puppy) and it took me about 2.5-3 hours. As long as you lay out all your pieces and keep them fairly organized, it shouldn’t be too bad. 
I do wish they had more colors available, but if you’re looking for something simple and durable, I’d definitely recommend these nightstands.
