Overall the desk itself is mostly great. I am 6'6" and it would never work for me as a standup desk, but for my wife who is 5'2", it is great! For the most part it feels sturdy and well put together. From unboxing to presenting her the finished switch-over from her previous desk was about 2.5 hours by myself. We have a monitor arm stand that means she has to lift from the back of the desk to it's standing position, but that is a minor annoyance. 

The in-between shelf has also helped her free herself from her cat overlord during her working hours, so that is extremely welcome!
