Works great for small rooms i.e kitchen, office or laundry room.
Works great but needs condensate (water) emptied (dumped on outside plants) every 10-12 hours if you can't use the "self drain" option. Had to check the low / high fan speed using a anemometers (yes I have one) because there wasn't much difference (2.7low and 3.3high). Reached out to customer service and that was correct (fan speed) because it's a smaller "home" unit, works as designed. The noise level is acceptable on High or Low. Only improvement would be an led down light in the reservoir to see the level in the catch tank. Photo - sitting next to a standard 20 inch box fan - level hard to see in a darker conditions. Because it's basically a "mini" ac unit (the instructions state that it does contain Freon and must be treated as such when repairing or disposal). It does generate some heat (no exhaust). It works way better than the "electronic heat sink" type of dehumidifiers.

Portable and Works Well in Subtropical Weather!
First, I live in subtropical weather where it’s humid between Spring-Summer-half of Fall. In the summer, humidity can be 75%. My ideal is 45%. I purchased this 1,500 Sq. Ft (21 Pints) Dehumidifier 15 months ago and I LOVE this thing! Even though it’s small, it has wheels you can add/remove to make it easier to move around the room. Portable and energy-efficient are ideal as I wanted something I can put on the floor or a table. So far, I have kept mine on the floor since it doesn’t take up space (it’s 16 inches tall with wheel; 15 inches without. Across it’s 9 inches wide. Depth is 6.875 inches). When it’s humid (60%-75%), I dump the water out twice a day—because it’s small, it’s much easier to maintain/manage. I prefer this over having to carry a big heavy bucket of water and spilling all over the place (the big ones are prohibitive—makes me lazy and unwilling to do the hard work, LOL). It does come with a tube if you want to hook it up to a drain. You can set and lock to your ideal humidity, or you can run continuously. These are the 2 settings I use, though there is also a timer (I did not test the timer). Fan speed is high and low. You should check and play with the settings because you can easily lock it. I was a little confused at first, as I couldn’t tell if it was locked to a certain humidity or if it was on continuous mode, but it’s my fault for not reading the manual. It doesn’t take a lot of time to figure out, but definitely play with it so you understand various settings. I lock mine at 45% as I don’t like it any drier than that. It will stop automatically if the water container is full so you don’t have to worry about leaks/overflow. There’s an indicator light that will tell you if it’s full (red) and needs to be emptied, or if humidity is high (green for dehumidifier on/running), or humidity is good (blue) and holding steady based on the locked setting. I added a short video of me dumping the water when container was 30% full. I highly recommend it if you’re in a subtropical climate and want something living room or bedroom-friendly (portable, manageable, and not an eye-sore). Space is 750 sq. ft and works just fine on its own. I track the humidity in every room using a hygrometer so am able to verify efficacy. I did contemplate spending money on a dehumidifier, but this was worth it. For one, it seemed cheaper compared to the other brands (I paid $140 at the time). The AC also doesn’t have to work as hard if you bring down the humidity, and this device is energy-efficient so it will save you money while bringing you comfort. I think this helped a lot with my allergies and can reduce sinus headaches from stuffiness. I mostly use it from Spring to Summer, and on rainy days in the Fall.

Too small and didn't do much
It is small and quiet but not powerful enough. This has a very small tank in the dehumidifier. You need a drain. The power cord and hose are very short. It is supposed to cover 1500 sq ft. It barely made a difference in the basement. The humidity was at 89% and it brought it down to 81%. I needed to get a different one. Update: the company reached out and sent a larger unit free of charge. It is doing the job.

Small unit - just what I was looking for HOWEVER it got delivered broke and unusable...
UPDATE: 08.24.26 - So the 2nd unit is working out wonderful. Its coming off and on as it should and collecting lots of moisture out of the RV. So far I'm very impressed how well this is doing for being a smaller machine. I obviously received a damaged, non working unit (not the sellers fault) the 1st time around and the 2nd unit is doing a wonderful job. I just might take my chances again and order me another one as my intentions was having 2 of these. Compared to others of its size, having a compressor, quietness and function ability - this one was priced reasonable. I ordered 2 of these brand new. The 1st one came a day ago so I unboxed it and let it sit upright for 24 hours. I read the instructions - seemed simple enough - plugged it in and it showed the humidity level then went straight to a "CODE EF" - After turning it off & on & unplugging it - still no fan or compressor movement. So with doing the side bar questions with Alexa, this was her response:: The EF error code combined with no compressor or fan movement indicates a serious hardware failure—likely a faulty compressor, motor, or internal electrical component. This is not something you can fix with troubleshooting. So with that said, I'm boxing it back up and already printed out my return label !! I just received the 2nd one today so it will be interesting to see if it will work - 1st I have to let it sit for 24 hours. So far I'm not having very good luck !! I bought these for use in my RV 5th wheeler 37ft. Another thing I'll mention is the lid to the water reserve - its hard to get the lid off as there is nothing to grab onto to get it off - kind of a wonky setup for over $100. Disappointed so far. Also, the unit was damaged when I got it as you can see the shipping carrier dropped the box and damaged it - probably the reason why its throwing a code and doesn't work !!!

Great for small spaces but not 1500sf
This works surprisingly well for such a small dehumidifier. But it wouldn't be enough to cover 1500 sq ft. I use it in my tiny RV. I'd recommend it for one room only, not 1500sf. It's quiet, the reservoir is easy to empty and easy to clean, unlike some others I've used.
