I just started using this today, but so far it's great. I'm 5'3" so it could go a little lower for a sitting position, but this is easily fixed by raising my desk chair a little bit. I like being able to set my two monitors a little further back and still have plenty of space for my wireless keyboard and 11x17 papers in front of the monitors. The powered motor is smooth and I haven't experienced any wobbling yet as other reviews have mentioned, although my desk is half on an area rug and half on hardwood floor. I would definitely recommend this item.
