I have the same one and it’s excellent, strongly recommend it.
Works great, only noise is the fan blowing air. Wifi and the app work great and connected seemlessly. Bought early June 2025, so a healthy year now, stored between Sept-May. Using it in a 5-600 sq/ft loft apartment. Would recommend it to anybody.
I have the reversible heat pump version of this one (mine’s a Midea, but the Danby is just the same thing rebadged), and it’s been going solid for years. I do recommend the heat pump one though it’s worth the extra cash especially if you have electric baseboard heat because it’ll save a ton of electric bill cost in the winter, plus be just as effective of an air conditioner in summer. Despite looking like a single hose from the outside this is actually a dual hose unit (they’re just nested inside eachother), so it doesn’t have the drawbacks of single hose ones. Avoid single hose, they pull the room down to negative pressure so heat leaks in from elsewhere and negates the whole point. My husband had to rig up some plywood and foam adapter to make it fit our window as the included plastic one doesn’t really work everywhere.
2 hose, same as the one OP posted, where the two hoses are nested inside one big oval shaped hose. The only thing that’s different about mine is it’s a reversible heat pump, so it can heat or cool. Also it’s worthwhile to put it up on a couple milk crates or something and get an automatic condensate pump from Home Depot, then connect it to the drain port on the back. A condensate pump is basically a little bucket with a float in it so it pumps out the condensate for you into a nearby sink (or outside or whatever) whenever it gets full. Without that you’ll be constantly emptying the built in water tray bucket thing. The top end portable units have a built in pump for that but I’ve never seen them on sale anywhere.
I have one, and it has saved me multiple times during hot summers. Great unit! Only con is the window attachment, flimsy plastic clips.
Where are you getting $800 from for the dual hose? Costco has a dual hose one on right now for $500, but often drops drown to 400/450. I have two of them and they've both lasted for years. If you own your home though, the window unit is a no brainer. Takes up zero space on the ground.
I unfortunately have 2 of these. Portable air conditioners are very inefficent. If you are going to use this to cool a small bedroom it will work fine. A comparable sized window conditioner will cool a much larger space.
