I love this for a little cooler to use when you sleep at night! It’s perfect to keep you at a good temperature. My only gripe is how small the water tank is. I have to keep a small cup by the nightstand to fill up if I happen to wake up and the light is blinking indicating its need for a refill. Otherwise, great purchase. I’m very happy with it!
I give this little wonder high ratings because it is so much better than expected. I've purchased (and returned) larger and much more expensive evaporative air coolers, and they did next to nothing. This unit, while small and needs to be pointed at you from a short distance, definitely cools. It's easy to fill and use (although I've not tried to clean it yet). I don't know if it will last, of course, but it appears to be well made. It won't cool like an air conditioner, but it will cool more than a standard fan. Those few degrees of cooling are quite a relief on hot days.
So far, the mini cooler does work to a certain extent. It is small and compact, therefore, it cannot cool an entire room. I'm just looking for it to do the job that my 'red-neck' cooler was doing for that last few years.
