Purchased this for our Camping Travel Trailer.  It’s cools wonderfully and the electronic controls have several nice features!  We have not yet experienced the heat option but there is no doubt that it’s equally effective as the cooling.  In the rather confined space of our camper we do have condensation on and around interior areas of the unit.  This is easily managed with a drip pan and the fact that we are camping on the beach (very high humidity).
