I just got this last Saturday and assembled it that night.  Used it all day Sunday for homework and Monday for "real" work and I LOVE it.  It goes low enough to use my balance ball for a chair or high enough to stand at it all day long comfortably.  It is pretty easy to assemble although it is heavy so some steps did require the assistance of my husband.  It is also big, which I love because I can now have three monitors going on my desk along with all my other desk things and not knock everything over all the time.  I would recommend this desk to anyone who is looking for a sit-stand desk, I don't know how much sitting I will do as I love standing, but this desk gives me the option and it is easy to raise and lower - and it is an amazing price compared to others that I looked at.
