Bests & Worsts Reviews from Amazon

just to clarify - this is a mini-evap cooler, aka swamp cooler. Works great in dry climates, not so great in more humid ones, and probably ineffective in very humid parts of the country. I have not tried to measure temp difference w/thermometer since the cooling effect is same as "wind chill" - cooling affect against human skin and a thermometer simply doesn't measure this. With fan on high, perceived cooling is very noticable. Regarding other comments re: poor fan output...fan has 4 speeds, maybe user(s) didn't get up to the high speed level...? I have mine on a table 5-6 ft away from my Fam room couch and moist cooling breeze is VERY noticeable and effective. I have been able to increase house A/C 77-79degrees during plopped down watching TV hours, or using laptop/ipad for extended periods. I used to have to set it at 74-75. Have saved quite a bit on electric bill. Portability isn't a big deal for my use, so wish it had a larger H2O tank. Need to refill every 3hrs or so, but this would be dictated by fan speed and environment humidity. I always run my fan on high and humidity is typically in low teens. Only thing keeping me from buying several units (bedroom, office, kitchen) is price. $80-99 is a little steep.
