The temperature setting is not what you might get from the unit. Tech support says there is a 5 degree swing + or - from what the thermostat is set. Also had a problem with the exhaust hose getting hot. I think this is why the thermostat is not accurate. The exhaust hose also will not stay in the window attachment and the tech support said to use duct tape to hold it in place. Design of the hose adapter to the window opening does not work. I have another brand and the hose stays in unless you release the clips. Do not recommend this item.

So the delivery was late on this item by several days. I guess that should have been the indicator to just return it. It is less than one year and the control unit has been replaced as the first one burned out and the second will not stay on the right setting. That is a $150 part. It is in a small office and takes some time to cool the room which still has hot spots. The exhaust hose assembly is total trash and falls out of the machine and the vent. It is not worth the $400.00 disappointing. I think the design flaw is condensation build up in the control unit causing it to fail.

I have a delonghi 4 in 1 (500) from 2018 that I really like and it is a 5 star unit. I decided to purchase this 3 in 1 (500) 2020 I went with the 3 in 1 since I will not use the heat function in this location. Boy did delonghi cheapen the part from the hose that snaps into the expanding piece that goes into the window. The plastic is so thin it bends. I was wondering why the bedroom temperature jumped up to 81' with the ac unit on. I looked behind the curtain and the plastic hose end had popped out of the window expansion piece so all the hot air was blowing up the window and not outside. After popping it back in it fell out again, seems as hot air comes out of unit the plastic gets even more pliable and will not stay locked in. I grabbed my industrial hot glue gun and glued the two pieces together. A regular temp glue will not hold as exhaust would melt it. I went to older unit to see if I could swap the pieces, well you can not delonghi changed the design from two pieces to one and the plastic is very noticeably thinner on the new unit. Performance of this unit is very good for a portable unit. FYI Portable units do not cool as well as window units of similar ratings. Delonghi did upgrade the remote control with temp setting on remote. This unit displays all information on top of the unit so you need this from a distance. The 2018 delonghi displays everything on the front panel but nothing on remote. Overall I would buy this unit again but very disappointed in delonghi quality on parts going down. I just hope they didn't cheapen the internal components as well. I own two Delonghi units and one 2019 Honeywell (400). I think the Delonghi units are nicer.

Best portable AC unit I've ever had until two days ago. Quiet. Rarely ran except on the hottest days which lately were more. Kept both the temperature and humidity sooo comfortable in an work room area. Then five months in, just died with a PF error code. Returned to Sams and buying a different unit, different brand.

Had this a month so far, works well. I use it in conjunction with ceiling fans to move the air around the downstairs.

Doesn't seem to get very cold, and does not cool my small living room. We had to buy a second window unit.

Bought this for my son's room in an apartment with no A/C. Works great for his room and helps a little with the rest of the apartment.

The unit never cooled. It was returned and exchanged for the old fashioned window models - which work very well.

We bought this last month. It was very easy to install and it is keeping us cool during this hot spell.

I bought this a few months ago have been using it when the temperature gets over 76 in the house. Cools 2 rooms easy.
