Workhorse and Quiet Enough
Been using this Amazon Basics 50-pint dehumidifier steadily for 3 weeks, and it is performing admirably on all accounts. Fairly quiet, really pulls the moisture out of the air, dependable, easy to empty and very easy to operate. I am considering purchasing another identical unit to keep as a back-up, should one be needed. Can't speak right now to energy efficiency. Appearance is, well, it looks very much like a dehumidifier!

Works great, Easy setup
Easy setup and operation. Ran units (2) in auto mode for 5 hrs and collected about a quart in both units. Dropping humidity to 47% from 65%. Quite satisfied with its effectiveness, noise is not an issue for me. Excellent space coverage considering size of unit. Unsure about quality and durability.

Pleasantly Surprised
This is an exceptional dehumidifier. It's been run hard for the three weeks that I've owned it. And it's worked terrifically. I was pleasantly surprised because the reviews indicated a lot of negative comments. In fact, one reviewer indicated that CR rated it at a very low 35 on its performance scale. These points notwithstanding, I still decided to go ahead and buy it because of my positive prior experience with another Amazon Basics product (a Microcut Shredder). I'm glad that I bought it. It's performed better than my old Home Labs dehumidifier, which was very highly rated by CR a few years ago. I use it in my combined Laundry and Utility Room which is adjacent to a crawl space, so there's lots of humidity in these areas. The dew point has hovered in the 70s or tropical humidity since early July so it's been tested hard. It has passed with flying colors. The Control Panel is straightforward and intuitive. I run it on Continuous Fan so it only stops for the water tank to be emptied. The Humidistat is very accurate and maintains a comfortable setting. The Filter Alert Light is accurate and reliable. The Water Tank is more than adequate. The Wheels on it make it easy to move to other areas. I definitely would buy this dehumidifier again and I highly recommend it to prospective buyers. The only caveat at this point is whether it will continue to perform well in the long run. [As such, I will update this review at a future date.]

Excellent performance, but handle with care
Did a LOT of looking before choosing this one. Good capacity and performance, Energy Star rating, and quiet operation. Great value, but treat it gently—the plastic enclosure won't survive a lot of abuse.

It works great...until it doesn't.
Conveniently, after the warranty ended, the dehumidifier would freeze up and develop ice on the back of the machine. I have ensured that the temperature in the room is not the cause, I've kept up with cleaning the filter and ensuring the back of the machine is also clean. I have also followed the recommended placement and the issue still persists. I will not be able to get my money back because, as previously stated, this conveniently falls outside of the warranty. I originally purchased this as a replacement for an older Amazon Basics Dehumidifier; I foolishly assumed I could continue to trust the brand. If you want a device that will work for 1 year and a few days, by all means buy this product. It's a great one-year rental. If you want to spend $200+ and expect something that works for several years. Look elsewhere.

Works Great
Love my dehumidifier. It has been getting the moisture out my home since I got it. I have a 2500 sq feet home and it covers the whole house. I haven’t seen moisture on my windows since I got it.

Made a Huge Difference in the Air Humidity of Our Home
While most homes tend to be extra dry during the winter months, our house seems to be ultra humid. With our windows shut to keep the cold out, our house seems to hold in all moisture, even despite having bathroom and kitchen fans on. Our humidity goes up to almost 75% according to our hydrometer, and even after opening all the windows during the day, we still wake up to moisture on the windows. The Amazon Basics Dehumidifier did a great job of dropping the humidity in our home and collecting all the extra moisture from the air. The water collected in the collection bin, was easy to empty out, and I could control everything at the push of the button on the top of the unit. You can set the humidifier to run for a specified amount of time, until a specific humidity is reached, or just as long as you need it to drop the humidity in a room. It operates about as loud as a fan, and the air that comes out is just slightly heated, but not so much that it warms a room. It works effectively enough to keep our home's moisture levels in check, and while it's a bit heavy, it has earned it's place in our home to keep our air a bit drier and windows and walls clear of moisture.

I like it!
I purchased two of these units, two years ago and am very happy with their performance. Kind of shocked at some of the bad reviews. On average days the humidity level will get down to the mid 30s with my machines. On very humid days both of my units will fill the 50 pint collection tank and keep the humidity in the lower 40s. The fan is fairly powerful, so I hear them come on and running, but it's not bothersome, and there are no aberrant noises. Moving to a bigger place so just purchased an additional unit. Will update my review in a few months.

This thing is incredibly efficient !
I did not want to buy an amazon basic product....BUT, I was looking for a unit with a pump that could empty the thing uphill as I have a pipe connection for it well above the ground. It works so far amazingly well (2 days I have it). It did remove all the humidity of the basement, and on top of this, I have a small leak (yet to be fixed) on water tank input pipe, that was dropping and slowly filling the safety reservoir. Well, the drops dry out on the pipe before reaching the ground :) So this thing is even emptying the water from the leak ! :P .... Definitely, if you look for a device that can auto empty its water tank, run 24/7 and keep basement dry, that's the one.

Drying out the must
We have more than enough humidity in the basement to use this every day.

Never worked from day one.
Cons: 1. poor packaging means this dehumidifier is susceptible to shipping damage. I got two units and both had the same top corner of the box and unit damage. My second shipment also had serious side box damage and the unit was dented and cracked. The damage was pre-shipping so not sure why amazon sent it in the first place?! 2. controls are confusing. The Manual seems to be complete, and yet I still feel lost with the various controls. Pros: there are no Pros...since the unit has never worked properly from day one. Plug it in, the controls light up. Turn it on, the machine runs. Eventually starts pumping out warn air. But after days...and weeks of running (trust me, I tried)...there is still no water in the reservoir. I have another similar Dehumidifer, thats I parked in the same room, and it collects 30l of water in a couple of days (humid basement)....but this Amazon Basics unit only collected about 1 ounce of water over 3 months (and that was probably due to natural condensation.

Pros and Cons
The unit essentially works well at removing room humidity. The issues against the unit are: CONS 1) The control panel display is difficult to see (tiny LEDs). 2) Also the Timer (Start and Run) function is difficult to understand and without use of the Owner Instruction Manual. 3) The Water Collection bucket is difficult to remove and especially troublesome to get back in place. 4) The Water Level Sensor arm sometimes drops down when the Water Bucket has been removed, care when replacing the bucket is necessary as that arm could have dropped and would easily then be broken. 5) The unit seems to cycle On / Off perhaps more than necessary and this is annoying. PROS Works well and is fairly quiet.
