Very wobbly even when the screws are tightened. I had to put something underneath one of the wheels to make it just bearably wobbly and not risk spilling my drink when I type. The bottom metal part does not look straight. I like the adjustable height though. 
The top wooden part was damaged during shipment, and Wayfair promptly sent me a replacement part at no additional cost, and I appreciate that. Otherwise, I would've given this desk only 2 stars.
