Well executed4
This dehumidifier will nicely done, and has several well executed details. For example:
Hose drain connect has a cap that can be replaced.
It includes a three foot hose.
The drip bucket has a handle inside it.
The whole unit has a handle on the top, making it easy to carry.
It has a basic filter on the back to prevent dust buildup on the coils.
It is reasonably quiet, at least compared with my 9 year old white-westinghouse. It might be too loud in a bedroom, but I can't hear it in my basement until I'm 2/3rds the way down the steps.
It is energy star rated, and (according to the manual) consumes 520 watts of energy.

I take one star away because water can drip into the bucket even if the hose is connected if it isn't leveled just right for the water to go down the hose. If you have it such that a little water gets into the bucket AND the hose, it may be a potential for mold growth. This is a design problem that is fairly easy to overcome once you are aware of it.

Hassle-free and effective5
I first became aware that I needed a humidifier when the condensation from my basement walls left mildewy puddles on the floor. My basement is about 900 square feet. I did a lot of research online, and although I couldn't find a review for the Haier, it had a lot of the features I was looking for (45-pint, Energy Star, Auto-Shut-off-when-full, price, etc). I left the settings on full at first; in one day there was no visible water, in two days there was no obvious dampness, and by the third or fourth day, I turned the settings to normal, and the unit began clicking off when it reached its target humidity level. Because it's in my basement, I'm not really aware of the noise, but it's quite a bit quieter than the air conditioning. If you compare it to your average box fan with three settings, I would say it's substantially quieter than the highest setting and a little bit louder than the medium setting. I've run it continuously since May and haven't noticed a huge difference in my electricity bills.

Stopped working after 9 months. Read Reviews Carefully!1
The positive reviews for this dehumidifier are most often from people who just started using it and are happy with the features. The fact is, I was happyt too until it stopped working after 9 months. There are 3 out of 14 reviews like that, one of which had it not work from the beginning. I would be interested to have people who wrote their reviews shortly after buying to update after 2 years of use. Even without this, 3/14 (over 20%) failure rate isn't good for one year of use!

I used this dehumidifier in the basement of my house. This worked fine and then stopped dehumidifying after 9 months. I don't feel that a dehumidifier should stop working after such a short period of time. I examined the inside: The compressor gets very hot and the cooling coils are not cold at all, except for a very small region of thin tubing connecting two banks of coils. Water condenses on this small portion but on no other part of the coils so total condensate is <1 ounce of water/12 hours. Deffective!
