Enjoying my new desk! Took 2 people an hour + to put together. There are 4 memory buttons and I only use two. Up/Down motion is smooth so far. 
The drawers are a little bit difficult to close all the way, maybe over time it will get easier. I used the wheels and those are plastic, but so far work fine on my tile floor. 
Two small disappointments:
1. Drawer handles are not black they are a silver- I might paint them
2. I thought this came with a wire basket. I see the holes in the desk, but did not receive the basket. Will need to figure something else out as it looks messy.

Would still buy again.
