The cranking and possible mechanical problems with that seem to be the disadvantage. I have found the Varidesk (<a href="http:&#x2F;&#x2F;varidesk.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;varidesk.com&#x2F;</a>) to be quite satisfactory. It sits on top of your normal desk and is adjustable in seconds. (I just own one; don&#x27;t work for or have investment in the company that makes it.)
