This desk is GREAT!ProsEasy Controls: The controls are straightforward and easy to operate. There is one button each for up and down, along with four user preferences.Quiet Motors: The motors are very quiet, making the adjustment process smooth and unobtrusive.Height Range: The desk height ranges from 28 inches to 47 inches, taking about 20 seconds to go from the lowest to the highest position.Sturdy Build: The desk is very firm, with only a slight wobble when fully raised.Ergonomic Benefits: As someone who does a lot of close-up work, I used to suffer from a sore back due to constant bending over. Now, if I want I can raise the desk to just below my chin, which has been a real back-saver.ConsAssembly Required: You have to assemble the desk yourself. While the lower part is relatively simple, you do need to drill about 20 holes on the bottom of the top unit. I had assumed it would be predrilled, but this method does ensure a perfect fit.Shipping: The desk arrives in two packages. The top unit arrived on the expected date, but the bottom assembly arrived a week later. This led us to think it was lost, and we spent time trying to contact the seller. Eventually, it all worked out.Overall, I am very happy with this purchase and highly recommend it!
