I hate weeding through the reviews for evaporative coolers because it seems like the majority of bad reviews are from people who have no clue what they are and what they are supposed to do, a few are from people who can't follow basic instructions, and there are only a handful of legitimate negative reviews that are usually due to defective issues.
I live in Denver, CO. It's dry here and it's the perfect climate for evaporative coolers. I've had whole-house swamp coolers in previous homes I've lived and know many friends with them. In my home, I have no option for a portable or window A/C air conditioner as I spend most of my time in our finished basement and there's not a good option for exhaust. Last summer we got quotes for central A/C but it's a lot more money than I want to spend and I also don't want the electricity bill that goes along with it. We have a whole house fan (not to be confused with an attic fan) that we run in early morning before it reaches 70 degrees and that we run again at night, usually after 9pm, or whenever it gets cool enough outside. Sometimes with an afternoon rain shower we turn it on sooner.
I bought the evaporative cooler to supplement the whole house fan on those reallllly hot days and/or for the middle of the day when we we're not running it due to it being hotter outside than it is inside. The house fan cools the ground floor much better than our basement due to the lack of air flow from our basement windows because of the window well covers we have. Also, this summer I'm pregnant with a due date of August 15th and that doesn't help my comfort situation. Basically, an evaporative cooler is exactly what I wanted and what fit our situation.
Think of it as a fan on steroids. Cold air DOES come out of it. Today it is 88 degrees outside and humidity is 16%... a typical Colorado summer day. I have the cooler about 3 feet away from me and 8 feet away from my husband. I have it on high and I'm actually getting cold. I have it on the "swing" setting otherwise I would probably turn it down. It doesn't guzzle through water too quickly and filling it once a day is enough since I'm not running it 24/7. I use a gallon pitcher to fill it up faster since it holds 10 liters (2.5 gallons). I have an automatic ice maker in my fridge so I don't have any issues running out of ice. I can't think of any features it's missing. It's not too loud even on high it's like a normal fan. There's no smell at all but I do actually change the water frequently and follow the cleaning instructions. Trust me on the smell thing, I can smell anything from very far away ever since I've been pregnant. You can wash the air filter on the back but DO NOT USE WATER to clean the wick. It is meant to be placed in direct sunlight to clean. I think that is why some other people had issues with smell or mold. Follow the directions, please. It has a remote, timers, sleep modes, swing function (just the fan blades inside swing, not the entire unit), warning beeps and visual indicators when it runs low on water (nice feature to avoid burning out the water pump), and an extra place to put ice on top in addition to putting ice in the water tank. You can adjust the blades on the front to direct the air flow whichever way you need to vertically. It also has an ionizer and you can run it as just a fan if you'd like, so no need for a second unit just to get some air circulating.
All in all... this thing does exactly what it says it will do. It's exactly what I wanted. It came assembled, which was a big bonus. It's only 17 lbs and has built in handles on the sides so I can actually carry it upstairs by myself if it's empty, even being super pregnant. It's on wheels to make it easier to push around when I don't have to take it to another floor. It was less than half what other similar units cost for the same tank size and air output.
I've only has this thing for a week. I will be sure to update my review once I've had it for awhile.
UPDATE 6/24 I've found that when I run this thing on high for 8-10 hours per day, we do need to fill it every day or every other day at the very least (depending on if I fill it to the max level... usually I just add 1 gallon when I fill it). However, when I'm running it on medium or low and not using it as much (more like 5-6 hours per day), it can last about a week without needing a refill. I typically don't bother putting ice in anymore unless it's a day with over 95 degree temperatures and I want extra cold air. The only thing I wish it had was an easy way to drain it in case I want to move it upstairs when it's not empty. However, I don't think any model I looked at had this feature (or at least it wasn't mentioned). It has NEVER made the room feel muggy even with no open windows and honestly I don't feel any difference in the humidity in the room. Almost every day it's been less than 20% humidity outside, and I've never seen it get over 30% outside. I'm still happy with this purchase and stand by my 5 stars. I'm glad I got this instead of spending much more on a similar unit.
UPDATE 6/25/2012 We didn't use this thing at all once it got cool out last fall. We drained it (easy to do while not pregnant) and put it in our basement storage closet. When we brought it back out a couple weeks ago, I vacuumed the screen on the back, filled it with water and drained it again to rinse it out. No musty smell or anything and it works just as well as last year. The room we normally are using this in stays pretty cool compared to the rest of the house, so now we're purchasing a wall-unit swamp cooler that is 5500 CFMs, hoping it will keep the entire house cool. The only thing I don't like about this cooler is that it's too short to feel it when laying in bed. You can tilt the blades up and down to direct airflow vertically, but it's not enough for a king size bed that's on a frame and box spring. For those of you wondering the electricity cost is negligible. I don't see any difference in our electricity consumption when we are using it every day compared to when we aren't. However, my husband and I work work full time so we don't use it as much as someone that doesn't work or works from home. I'm still happy with this purchase and thing it's a great portable swamp cooler for the price!
Also, here's a chart that shows evaporative cooler effectiveness based off outside temperature and humidity. I will also post it to the pictures.
I live in California in the Bay Area. Not much humidity and the weather is typically pretty mild but it does get pretty hot in the summer (90+ degrees). I received the unit on a particularly hot day recently and I ran out and grabbed a bag of ice because i wanted to test this things cooling capability. I set it up next to my computer desk and turned on the cool air function. I was sitting about 5 feet from it and in 5 minutes my arm was freezing cold. I was perfectly comfortable the whole day but if i moved from the fan at all the heat was unbearable. This thing does not cool a room but it will cool the area directly in front of it. Once it cooled down a bit I emptied the water (which was made very easy due to the lightness of the unit) into my bathroom sink and used it that night as a normal fan. Its pretty quiet and the fan is powerful. Ive heard these swamp coolers can generate a musty smell so I make sure to empty it of water when I'm done using the cool air function. I only fill it with water when its extremely hot because the fan works fine for me most days. It's a very nice unit and it's exactly what I was looking for. Better than a fan and more efficient that an air conditioner.

This unit is design for about a 12 X 12 foot room and can help a hot day be livable. Being able to add ice into the water trough and an ice pack into the top can lower the temperature 5-10 degrees (F). The only minor draw back is it increases humidity, my doctor would not call it a negative, which on an extremely hot day can make you feel sticky. This unit is really good in desert/low humidity geographic areas.

To be fair, the product does not claim to be an air conditioner. However, it does claim to cool 12 degrees cooler, which I didn't find at all. I live in a dry Colorado climate, and still it is barely cooler than a fan. You have to fill it with tons of ice to even get that, and it requires refilling with water and ice often. If you don't clean it at least once a week, it starts smelling really bad.
All this effort of refilling and cleaning is not worth the 3 to 5 degrees cooler you get. For that, I'd rather just plug in a fan and not have to worry about it every day. Save your money and buy a portable air conditioner. It's worth the extra investment, trust me.

My wife and I currently live in one of the hottest, driest places in the U.S. -Las Vegas, NV. Our apartment is mostly shaded and facing away from the direct sun, except for... the HOT room. Our office. "The hot room" faces the south-west side and gets beaten by the direct sun. This little unit is PERFECT for that room. It does a great job of turning the hot room (which is also the room we are in the most) into just another room in the apartment. Now I don't rely on this unit alone to single-handedly take on all 110 degree of Las Vegas heat, but I don't expect it to. It simply does what is intended. It brings the temperature down 10-15 degrees in the room that is generally 10-15 warmer than the rest of the apartment.
So, if you live in a region with hot DRY weather (most of California, Nevada, Arizona, New Mexico), these can supplement your AC, put some moisture in the air and take a nice chunk out of your monthly Air Conditioning bill.
If you live on the East coast, the southern states, the Midwest or any place HUMID, DON'T BUY THIS. It wont do a thing and will probably just make the muggy, oppressive heat WORSE. You've been warned... I lived in Miami for 5 years and understand that 90 degrees in Florida is WORSE than 110 degrees in Las Vegas. This is because of the HUMIDITY, not the HEAT. You don't see "swamp coolers" in Florida because they just add humidity to the air, and that would just make matters worse.
For those who may still be a little puzzled by these and seem to think they're some kind of portable air conditioner... they're not. This is a smaller, updated version of the traditional "swamp cooler" that has been in use on the U.S. west coast & southwest for decades. These work great... IN DRY CLIMATES ONLY!
As a kid growing up in central California, the "swamp cooler" was our ONLY way of keeping cool during the hot, dry summers. Back then, everyone had the BIG, dish washer sized swamp coolers on their roofs or hanging out of their windows. Many people still use them to this day. So how exactly does this mini "swamp cooler" work?
Put a fan in a box. Have some little screens (cooler pads) built into the sides of the box. Pump water over the screens. When the fan blows through the wet pads, it creates a nice, cool breeze. Now, Instead of raking out big money to constantly keep the central AC blasting away, this will use the same amount of energy that a regular house fan uses... a mere 60 watts! That's about 1/5 of what an AC of the same size would use! If you have one of these running in the room were you spend most of your time... and turn the thermostat UP in the rooms that aren't being used, you can save yourself some serious money.
There are quite a few features on this version that I think are great. Remote control, timer, "swing" (shifts the air in the same manor that an oscillating fan does), as well as an emergency "BEEP!" that sounds when the water level is low. The sf-609 also has an ION air purifier feature (I honestly don't notice it one way or another). After checking out the manufacture's website, I believe the only difference between the SF-608 & SF-609 is that the 608 doesn't have the ION gizmo.
The added ice tray on top really is kind of nice too and helps to feed melted ice water over the pads. This will bring the temp down another few degrees, and every little bit helps. Having an automatic ice maker in your fridge will help keep the top tray fed. If you don't have one though, you can away make ice the old fashioned way with empty drink containers. Adding ice really isn't essential though, but it does help a little and can get you closer to AC-like coolness. Another trick I use is to put 2-1 gallon water jugs in the fridge and use them to keep my water nice and frosty.
About the only thing I don't like about this unit so far is that it's a little "plasticy" & seems kind of cheaply made. For $100, they could have made it a little more sturdy. But then, that's how it goes these days... It's pretty much (or in this case COMPLETELY) impossible to find products that are built to last. They just don't make 'em like they used to.
At any rate though, I'm happy with this purchase. I would recommend this to anyone in a dry climate who spends a lot of time in a small to medium sized bedroom.
Stay cool ;)

First off I want to say that I did like the design of this unit. It was an interesting shape which did look cool on my dresser. I liked the fact that it was tall, so that the mist was released higher into the room. The oscillating nozzle at the top was great for dispersing the mist throughout the room. It also produced a good amount of mist at the highest setting.
