Customer Reviews

“Customer Review: I got this item and it works great! I even bought another one for my kids room, and it’s been a big help during the hot summer days. The included ice packs don’t make much difference, so I freeze thin rectangular containers of water instead and add with water to the fill line—it cools the room nice.”

“Customer Review: It is a glorified fan—it will only cool down your room maybe a degree with ice packs. For the extra cost, buy a real air conditioner that doesn’t need ice…”

Customer Reviews

“Customer Review: Yes we are using it, because it is better than nothing. It really is not worth the 200+ that we paid for. The commercial shows it compared to an AC, but it does not really do that good. It is worth over $50.00 but not the $200.00+ we paid.”

Customer Reviews

“Customer Review: Purchased this for a dorm room that doesn’t have air conditioning. It was easy to put together. The chill bottles are small, fit easily in a small dorm fridge/freezer and when used with the water tank in the air conditioner, they really helped to immediately cool the room! The fill tank is small,”

“Customer Review: Does not cool… my understanding was that it was an AC unit as it was described. It is only an evaporative cooler. BUT does not cool! It’s putting humidity into the air and the air output stayed very warm and I had to run a humidifier as was putting so much humidity into the air.”
