The desk looks great, is quiet in operation, and the four "height memories" are super useful for shifting between sitting and standing heights for a couple of people. The desk goes far higher and lower than I need it to go for daily use - it's got a really impressive range.
Even at full height (which I do use on occasion if I need to get underneath the desk), the desk is really stable. I also have the heavy-duty castors installed, and with the wheels locked the desk is rock solid, even with a monitor and 17kg desktop PC sitting on top.
