Great product
I purchased a second one for my home. The first one worked so well in living room, I needed another for the bedroom. Compact and easy to use.

Awesome!!!
This unit is so much better than the previous one I had. It has awesome features like the LED off so the glow doesn't keep me up at night. It's much quieter and packs a punch, came with all the accessories I needed to get it installed and more. Looking forward to cool days in the future! 😎

Great unit two switch from room to room.
[This review was collected as part of a promotion.] I've had this for a week. It is exactly what I need for my smaller room. And it's very easy to transfer from the small room to my medium room when needed. My daughter even likes the option to turn off the LED for bedtime.

All expectations were met!!!
I bought this product exactly 2 weeks ago. I can say that this is a perfect buy if you are looking to buy a portable ac. The sound is tolerable. You can sleep well at night. It cools the room whether you use the cool or dry mode. I was surprised to know that the dry mode can cool the room and the noise level is low. I am planning to buy another one for my garage before the official summer starts. I will definitely recommend this product 100%.

Perfect portable AC unti for bedroom
This unit was easy to ventilate. It cooled my large bedroom quickly. It is a not very quiet but it sounds like white noise so it was relaxing to listen to. It has a great adjustable vent. Controls were easy to adjust temperature. I would recommend and would buy another unit for another bedroom if needed.

Misleading details
Got this since it cools up to 300 Sq ft but received it and it clearly says up to 215 Sq ft on the box. Suggest getting another brand, you can get one the same price that cools a larger area.

Fantastic Portable AC combo unit
Just received this portable AC combo unit in the mail last week, just in time for some unseasonable warm Florida weather. I only run it at night…. It’s cools my bedroom down quick and keeps the room cool all night, kicking off/on as needed.

Junk
Bought the unit in April and it didn't even last the whole summer. The unit started leaking randomly and couldn't be resolved. Do not waste your money.

Good little machine with a loud compressor
Great size for a bedroom, cools well and quickly, has a continuous fan setting and you can turn the lights off at night. The window kit is a thick plastic unlike some brands but the hose clicks in and there are tiny gaps. My main problem is that the compressor turning on and off, is a loud thump, woke me out of a deep sleep and easily wakes me out of light sleep. If I’m awake it startles me. It’s super annoying and disruptive.

Perfect!
We bought this unit for our cottage. Our adult children each have their own room, and only one visits at a time. So this unit can roll from one room to the other, wherever it’s needed. This summer has been a scorcher, and they are so happy to finally have AC. It is easy to hook up to the window, and can store in a closet when not in use. It really works well. We are extremely pleased with our purchase.

Great little portable AC with small footprint!
This unit easily cools and dries a 13x11 bedroom. You can attach a hose to the rear, located midway up the back side so that gravity works in your favor. However, I had to buy the hose to attach separately, as it did not arrive in the box. It is also relatively quiet compared to the very loud 8000 BTU system ( (ARC-08WB) that I bought last year, and which is almost useless.
