Review Title: Great little heater
Comments: I would first like to say that the customer service at Air Conditioner Home is the best in the business. I am currently deployed to Afghanistan and the one drawback is that the winters here are very cold and the heat in out B-Huts is not very good! Matter of fact on most days you can see your breath in your living area. My room is a (7 ft x 7ft) palace with not very good power capacity and no insulation. I bought this NewAir AH-400 with the hope that it would help take the chill out of the air... well it has done that and more! This little heater is a Giant for it's price and low power consumption. I would say that if you need a small room or a personal space heater this is the perfect one!! P.S. Also if you have a space or storage issue's like I do don't pass up the NewAir AH-400.

Review Title: Portable Space Heater
Comments: Product is fine as far as how well it works, price is good. However packaging was not great - item has a crack in it, does not hamper operation, but packaging could be a little sturder to avoid this.

Review Title: NewAir AH-400 Portable Space Heater From Air & Water, Inc.
Comments: Love this portable heater and the heat it puts out for its small size! This heater takes up very little space and is easily picked up with one hand to be moved. It is the only heat source I am using to heat my fish room. The room measures 10' by 16'. It holds the temperature at 65 degrees with an outside temperature of 32 degrees. This heater does not heat up the cord or plug in like previous heaters I have used. Other heaters have worried me sick that I would have a fire. Unlike other portable oil filled heaters I've used over the years, this heater has a heavy duty cord and a grounded plug in. Buying from Air & Water, Inc. was a very painless experience. Easy to order, fast shipping, and a great product! I'll buy again and tell my friends and family about their products and service.

Review Title: Portable space heater
Comments: This heater fits in a small space and is very powerful in a small room like a bathroom. Only drawback on the previous unit - I believe it was a Dakota brand but same style - was that the bottom legs fell off, apparently overheated the plastic and they crumbled. It lasted about 6 years and the switch fell off, and the unit quit working. Other than that this is a wonderful small unit and I wouldn't be without one like this.

Comments: I would recommend it, as it's one of the few personal heaters that are recommended by hospitals & office buildings due to it's low wattage pull on breakers.

Comments: I needed a heater that heated without a fan because I have pets that like to sleep in front of a heater but are frightened by fan activity and won't go near such a heater. Fan-less floor heaters are very hard to find. So far, the heater is performing very well although the cold weather hasn't started yet. I would recommend it to anyone with cold feet and chilly pets.

Comments: It is great. The building management issued an edict that any space heater of 800 watts or more would be confiscated. A lot of our folks use these heaters to help them cope with the building A/C inconsistencies. This product has helped them while at the same time is compliant with building management's decree. I think I have directly purchased for others a total of 8 units and inspired at least 2 more.
