This is my second adjustable height desk; the first one was returned as it was terrible (and cost twice as much as this one).  This desk is excellent.  VERY sturdy and well put together.  Adjusts flawlessly.  I'm 6'5" tall and this desk goes up higher than I'd use, which is amazing; also I can't adjust it fully low as my knees wouldn't fit.  This desk has an amazing height range that is perfect for anyone under 7' tall.  Desk does not move AT ALL when I'm typing away at 50 wpm.  The desk also has two grounded outlets and 2 USB ports, along with the large drawer.  I definitely recommend.  Easy to put together and quality parts.  I wish they made a matching side credenza and other office furniture to match.
