  • Great Cooling Option for Hot Summer Nights
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 than add with water to the fill line, it cools the room nicely. It does take a minute to really start cooling, but once it’s going, the room stays much more comfortable throughout the night. I’ve also found that keeping it on the low setting makes the water last longer before refilling. Overall, a great alternative to a traditional air conditioner for windowless rooms. ... show more

  • Glorified fan is all it is.
It is a glorified fan it will only cool down your room maybe a degree with ice packs that com we with it for the extra cost buy a real air conditioner that doesn't need ice...

  • Fan, not AC
I would call this more of a fan than an air conditioner. It’s easy to use, although the drawer for the water doesn’t actually remove, so you’ll need to use a pitcher to refill it. The ice packs definitely help with the cooling, but without those, it’s moderately efficient to cool a room. The noise is also moderate, but I sleep with a fan and appreciate the white noise effect. The design is nice and compact. Without needing a window vent and the fact that it has wheels makes it highly mobile and easy to relocate. All in all it’s fine. I can’t really expect much more for the price, but had hoped it would make more of a difference cooling upstairs bedrooms (roughly 120sq ft each, bought one unit per room). ... show more

  • Easy to fill with water
Really does a good job of lowering the temperature, especially compared to other fans. The remote control is very handy and the water tanks are easy to remove and fill.
