Pros: ICE cold air, relatively lightweight, did I mention ICE cold air?
Cons: No drain hole, easy to fix, read below.
I paid $99.00 for this at Wal-Mart in 2005, and it has been used off and on since. I have central air in my current house, but I keep this one running in my shed.
READ: Country...dust from farm equipment picking crops around my property, and grass from my lawnmower every week. for most people, they know that = DEATH.
Well, this little bugger has held up through it all. The air is ICE COLD coming out of it, literally. It's so cold, that if you put your face in the vent, your lungs will not let you breath in, it's so cold.
The ONE MAJOR downside to this machine, is there is NO drain hole. = They never intended it to last more than a few years. If water can't drain it's sits. And rusts. Very bad for any A/C system. Well, that's easily fixable.
No one should be stupid enough to think "hey, I'll just drill a hole..." Great way to puncture something, and ruin it.
What I did, was remove the two screws (Phillips) on each side of the back of the unit, and bend the panel down. (It's OK)
Then, with a drill, drill (2) holes, probably 1/8" drill bit (I think that's what I used) and then either install little 1/8" rubber grommets (Home Depot, Lowe's etc have them), or get a little tar, and smear the holes. Why? So the bare metal doesn't rust out over the years. Then, rebend the panel up, and re-insert screws. All the water drains out, and no rust forms.
Other than that little issue, which really isn't a big deal, this is a great investment.
All the noise complaints below, are because of water pooling up and hitting the fit, making that noise. Make 2 drain holes, it will be very quiet.
Also, I am rating it as durable. As long as you make a drain hole, it'll be perfect. If you choose not to, expect it to last 4-5 years tops.
