Great so far

Shipping was very quick. Assembly was straightforward and the instructions were clear. All required parts were present and in perfect condition. The desk is quite sturdy at standing height (for me). The legs (black) have what I would classify as a semi-gloss finish. The power cords and connections seem robust. Overall I'm very satisfied with my initial impression of the desk. Hopefully it will last a long time.

My only suggestion for improvement so far is that the picture of the control on the product page on the website shows a control paddle with the desk height displayed on it (a woman's hand, paddle says "28.1"). This led me to believe that this desk included the programmable paddle. However it came with a non-programmable, non-display up/down control only. The product description does say "simple paddle height" but that is fairly ambiguous. The text on the product page should be more clear and/or the photo changed to represent what we're actually buying. Giving customers the option of purchasing either control would be even better.
