For the price this desk is great. It's got a high-quality coated metal frame, good hardware, and great assembly instructions. I had it assembled in under an hour, by myself. No assembly issues at all. Even the packaging was great with no messy styrofoam.

The up and down works great, quick and quiet, and the upper-most height is perfect for me, and I'm 6'-2".

The desk surface leaves a little to be desired with kind of a cheap feeling texture (in black anyway). 

For the price, I'm super happy with it.
