Rated 3.5 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by See my review of the GREE 12,000 BTU Neo Unit for more detail. This product works like it says it should with the gree mini-spit unit. My only complaints are that it should come with some sort of protective sleeve for the wall so that the insulation doesn't get damaged, and that it should come with a water-proof electrical connection for the exterior condenser. I can't figure out why these wouldn't be includes in the cost. Speaking of cost, I think $200 is a little steep for what you're getting here. December 10, 2013
Rated 3.0 out of 5.0 by Additional labor/equipment needed Although the quality of this piping set seems very good, the fittings on either end did NOT fit either the inside unit or the outside unit. The air conditioning maintenance man had to remove the attached fittings and weld in the correct size fittings. He asked if any adapters were packed in the box, but there was NOTHING else. Prepare to pay extra to hook up the piping set with additional parts needed. May 6, 2014
