Bill,
I posted a thread here about the same thing. I got one last week from my father-in-law for fathers day....( I have no children and have often wondered why I get a fathers day gift from him, but why fight it right?) He is sensitive and gets ticked when you return stuff, so I kept it. I was told I needed an 18,000 BTU unit. This is 12,000 and is truly inadequate. I saw one yesterday at Lowes just like it, it was their largest unit. I used it Sunday, it was 92 outdoors and the shop was kept at 83 all day. It did go up when I ran the DC and air cleaners...but it took the humidity out of the space, and was somewhat comfortable.
It comes with a 4 foot hose that needs to be vented to a window, and uses a DC type hose.
Again, it was free to me, and did help some..I am going continue to mess with it....
