This unit works far better than the one we originally had! Our apartment/office is 700 sq ft exactly, which this unit is rated for. It keeps up as best it can, but it can reach 80 degrees in the apartment on a very hot day (we can see up to 112 degrees where we live). To be fair, our apartment doesn't have the best insulation. It does cool it off well at night, and we can turn it off for a few hours/day (late night/early morning) which is nice, but otherwise it is constantly running. So yes, I would recommend it.
