This is the first portable air conditioner I've purchased. I've always been a window unit guy but we needed something for a pretty large space where the only windows were largely covered by a sofa - we needed something more flexible. I was torn between DeLonghi and Whilpool, but the sleek look of DeLonghi just caught my eye more. Setup was pretty easy. Only complaints were that screwing the hose fittings onto the flexible hose was a bit annoying (reverse threaded) and when locking the window vent into place, the little plastic locking mechanism didn't want to stay in place very well. All-in-all, it probably took me about 25 minutes to unpackage, sort parts, hook things up and have it turned on. I was expecting it to be louder than it is....it's pretty quiet and seems to be plenty powerful. We'll see if it can keep up with keeping things cool for us!

exhaust hose way to short Delonghi said no fix can`t help me POOR SERVICE called Delonghi they said a lot of people have called and complained about how short it is Delonghi recommend other brands with longer hose will never buy a Delonghi Product PERIOD !!!!

This works great up to around 90 degrees outside. However, once it gets HOT out, it runs very inefficiently. The exhaust tube gets hot enough to burn you. I had to spend the money and time to wrap the tubing with duct insulation after coming home to 103 degrees INSIDE. I've had to TAPE the connections to keep them from simply falling off and venting the heat directly back into the room. The exhaust tube is only 5 feel long and a non-standard size to extend it - 5.9" not 5" and not 6". If you're windows are not vertical sliding closure, you WILL have to figure out how to mount the exhaust in your window yourself...hope to don't have older windows like manual swing in or hand crank windows. I do recommend this unit, but be prepared to do some home engineering, or even Jerry rigging.

Out of the box less than 24 hours and this unit is clearly defective. Blowing, but not cold air. All controls seem to work fine. The compressor will OCCASIONALLY turn on (unit set to 70, interior temp 84, room size approx 500sq ft), but almost immediately shuts off. Exhaust hosing is cool to the touch. Clearly the fan to cool the compressor is not working (you can see that it isn't spinning) at all. So, just a glorified fan. Honestly not interested in what the warranty will cover if it is broken out of the box.

I recently purchased and I was not happy with method of delivery. I reside on the first floor and the AC was left on my front porch the driver failed to even attempt to place in the building hall way. The box is clearly marker stating what it is. This was very very heavy. When I read the reviews it said it could cool what would be a two car garage. This was not the case. I had a difficult time assembling.

Didn't work for Us

You really can't beat the deal. I bought one to cool the master bedroom in this crazy Texas heat wave. My husband struggles to sleep in any temperature above 70°… he is loving this Pinguino AC. It's actually cold in here. He has told me he's had the best sleep since I installed this unit. The only comment I have is I wish I could dim the control panel lights, but my husband told me if I just close my eyes and go to sleep I wouldn't have to worry about that. lol He would give the unit 10 stars if he could. For the price, I don't think you can get a better unit.

Very efficient

Does not cool the room.

I just purchased this unit and am very disappointed with the inadequate window kit that does not fit properly in any standard sized window in my house. The window kit is so flimsy and leaves gaps on the top and bottom. The plastic the it is made of is no better quality that a DVD case. Compared to to unit I was shocked that the company would include such an inferior window kit with it. I recommend the unit but I'm going to have to figure out something better for the window.
