I ultimately returned this - just due to the size. I didn’t measure as closely as needed and this was just too big for my needs. Build quality- I’d give it a 5 out 10. Other reviews compare the plastic product to something you’d pick up at a dollar store. I don’t disagree with that. Seemed to function as expected. Drawers slide out without sticking. It does look good- crisp clean appearance. No assembly required. Value for the money? No- I don’t think so. That’s my reasoning for 4 stars- cost is too high for the mediocre quality
