This portable air conditioner offers quick cooling and is easy to install, making it a convenient choice for guests looking to beat the heat. However, many guests have reported issues with noise levels, water leakage, and ineffective cooling in larger spaces. While it has some strong features like a powerful airflow and a dehumidifier function, the overall reliability and design have raised concerns among users, leading to mixed experiences.

Pretty good for the price
Brought one about three years ago and the fan crapped out so for three years its pretty good pretty strong but the life time is a bit short in my opinion.

Great AC unit
We used this unit to cool our server room. It was getting too hot and this was the perfect size and works great. We did find that we needed to use the external hose because of the amount of condensation.

Works for what I need
I keep it in 76-78 and it works to cool my office. I empty a bucket every 2-3 days. Satisfied for my needs

Broke quickly
I bought this at the end of the summer in 2022, so I used it for only a couple of weeks, used it all summer last year, and it broke immediately this summer. For over $300 this is absolutely not worth your money. I am very hot in my apartment and very upset, as is my dog.

Disastrous unit.
This unit is a pain. First, the tubing to vent out the window is an eyesore. The unit itself is large and trying to find a good location for it and the tubing is next to impossible. It does cool my room but it's so loud. Even in sleep/quiet mode it's pretty loud. Maybe if it were in a larger room the noise wouldn't be so noticeable. When I used the dehumidifier mode, the reservoir filled very quickly and the supplied hose doesn't fit the drain holes. Finally, the window attachment is too long for my windows. This machine need a redesign.

DO NOT BUY
Getting the vent piece that fits into the back and feeds air outside to stay connected to the unit is IMPOSSIBLE. It does not stay connected, rendering the machine useless The AC unit fills up with water so fast that it doesn't even get to cool the room before shutting itself off because it is "full". Manually draining the involves disconnecting the tube, which is impossible to re-connect. It has insofar been ineffective to cool down our very small living room, as stated above, before shutting itself off. A vicious feedback loop of frustration all while still baking in an intensely hot room that the unit failed to cool down even one degree. DON'T BUY.

It's Great However....
The unit is a nice size, however it is VERY disappointing that the grill in the front is blocked. Only HALF of the vent is open, limiting the air flow. I had an AC similar and it was able to cool most of my apartment. I do need to buy another unit just to cool my home. Other than that, the air flow is pretty powerful for the little space it has to flow out of. I enjoy being able to set a timer and the design is pretty nice.

Failed expectations
We were thrilled with the product's performance on the first day, exceeding our expectations. However, our excitement was short-lived. Despite trying various troubleshooting methods, including emptying the water, checking the tube placement, and ensuring a flat surface, the device refused to start on the second day. The device made a disconcerting sparkling, gurgling noise, which was alarming. We faced additional challenges, including: - Inaccurate fit of the hose for draining water - No water drainer bucket or saucer included - Heavy weight - Noticeable noise during sleep mode (though quiet) Given the excessive heat and humidity, we decided to return the product due to the hassle. Despite our initial love for it, the issues outweighed the benefits. I give this product 3 stars, hoping that the manufacturer addresses these concerns in future designs. *Additional Note* My cats were also disturbed by the device's sound, which might be a consideration for pet owners.

Loud but works
This is the loudest, most rattling air conditioner I've ever owned (and I've owned some cheap ones). Installation was fine; it doesn't fit ALL window widths it claims in the description unless you have the tools to cut one of the plastic components. Definitely disappointed

Poorly designed
The dehumidifier fills up after an hour. There is no drawer to empty the dehumidifier and no way to place something underneath it to drain into. The hose is useless. There is no way to clean the dehumidifier bin. In order to drain you have to lift the giant unit onto a bench to drain into a bucket. sorry, but I had to return which was a huge hassle because it's so large.

Need to drain constantly
For the first few days I noticed a smell in my apartment and thought it was a burst pipe in another apartment bc it smelled like sewage but after some experimenting I noticed it was the AC and so I drained both the ports which by the way was tricky and the top port has a major design flaw, the reserve I assume is very small because it didnt have much in the drain to drain but I noticed if I have it on a platform of sorts and leave the bottom drain stopper out with a bowl or bucket underneath for constant drainage then the smell goes away and it works fine. So if anyone buys this and notices a smell it's not ur apartment it's the water system in the AC other than that it works wonderfully but I don't know how the dehumidifier feature works and with a small reserve I don't know if I want to find out.

AWFUL - doesnt work + super difficult to install
i bought this for my room since it gets so hot, and it took forever to assemble! then, the window panel is too small for my window, and no matter what I did to fix it, the AC would still shut off after 30 seconds. i tried everything, and I can't even return it now. Do not buy this.

It's the right choice
This mobile air conditioner is highly recommended. The cooling effect is very fast. The spare parts are also very easy to install. The whole living room soon cooled down. It's a pleasure to buy a product that you can trust

Nice little cooling AC
This is our second summer using these portable AC units. We bought two. One for upstairs master bedroom and one for downstairs living room. We live in New England and don't have central AC. This is my first time living in a home without central AC. These units are great for those New England days that get into the upper 80's and 90's. So they don't get run that often. Probably less than 30 days per year and only a few hours on those days. The only reason I give it 4 stars is because the units are quirky. Turning on the power button somehow kicked one into "Dehumidifying" mode instead of staying in "Cool" mode. And somehow, I have locked the controls for the upstairs one. It only turns on with the remote instead of being able to use the power button on the machine itself. I probably hit the wrong sequence of buttons. I need to check the manual again. Overall, very pleased!

Impossible to assemble and way too large
Impossible to assemble and it’s so hot out. The tube will not connect to the other parts. It’s also a massive unit and takes up as much space as an office chair. You need the tube to use the air conditioner otherwise it’s blowing hot air so needs to be near a window and is a total nightmare. It’s too heavy to return. Do not buy this!!

Nice portable air conditioner
This product was more than i expected. Cools fast and is not too loud pretty quiet. The unit itself was easy to set up, and works great for cooling the bedroom very quickly.
