Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

GREAT concept AND fantastic customer service by Christine

By  from Los Altos, CA
Overall Rating: ☆☆☆☆☆ ★★★★★ 5

Recommended Product:

Christine was the utmost courteous and polished professional who knew exactly where the feet or casters (sans wheels) for their brand NewAir desk heater. When I called she informed me immediately that most call reporting them missing but in fact, they are cleverly hidden in space efficient packaging. I wasn't certain with what I was impressed with more, the clever packaging (tis really of all I have seen- as they were hidden underneath and embedded in the styrofoam fit snugly in the box) or Christine's knowledge of the product right to the packaging, helpfulness, and courteousness. It truly is difficult to get high marks in all 3 but she deserves them all. I did not have to wait for an additional shipment nor be directed to call another number where the heater is made, etc.. Time is precious ! The desk heater in itself is an efficient, perfect addition to a 8'.5 x 7.5' area converted into an office. It warms up the area just as well as the 700-800W space heaters but 1/2 wattage and is easy to maneuver. Best of all, I never regret buying it since I previously had the larger one which I would constantly move out of the way.

For the price of burning 4 lightbulbs I can keep pipes from freezing in a small travel trailer.

Great heating as well as low energy consumption

By  from Pittsburgh
Overall Rating: ☆☆☆☆☆ ★★★★★ 5

Recommended Product:

This is a good alternative to high heating bills, yet delivers heat for small to average size rooms, entry hallways or larger bathrooms. Keep heater away from anything close to the unit to prevent melting of objects. Feet need to be properly placed on unit and there is a click when locked feet are in place. Remove the clear warning labels first before initial use

NewAir AH-400

By  from Virginia
Overall Rating: ☆☆☆☆☆ ★★★★★ 5

Recommended Product:

The NewAir-400 is just what I needed under my desk. Every other heater I tried failed at keeping a constant comfort level. I would get too hot and then have to shut it off. But not with the NewAir-400, I have been comfy all the time. We even purchased a second for another co-worker.

These are the only space heaters our building management allows due to the automatic shut off and completely enclosed heating elements. We have over 15 of them in our office.

Under desk but 3 feet from furniture??

By  from Florida
Overall Rating: ☆☆☆☆☆ ★★★★★ 3

You need to remove the statement in the owner's manual that says to locate it 3 feet from walls and furniture if you are going to call it an "Underdesk Heater".
