This desk is one of the best products i have purchased in quite a few years, and i must say i have purchased quite a bit.  It is well balanced at the lowest level without a shudder and even at the height required for a 6.0' user there is very reasonable stability when pushed to the side.  The dual motors gives it a very smooth low noise operation when required.  The position selector has 4 four memory settings and seem to respond when those switches are seslected... Assembley will require two people, mostly to flip when needed, but the overall process will only need one.  The screw holes appear to be very solid so that one would have to work extra hard to wear out the install screw heads mounte in the table base.  Overall i would buy this product again and recommend to all my friends.  Great piece of furniture..
