AH400 Newair Portable Oil Filled Space Heater with Power Indicator Light, Built in Thermostat and Manual Controls in White is rated 4.8 out of 5 by 62.
Rated 5 out of 5 by from Great energy efficient slim line radiator style portable hea This afforably priced little heater looks like the modern slim-line radiators you encounter in Europe. It is great for small rooms (up to 150 square feet) and tight spaces. Like other oil filled radiators it is slient and less drying than fan forced heaters. Unlike other oil filled radiators it is small, wafer thin, and stylish. Also at 400 watts it is also extremely energy efficient. The thermostat could be a bit more accurate but otherwise the unit is well constructed. I hope to see similar thin radiators for larger spaces in the future. For now two of these will still save you energy $ over most other space heaters.

Rated 5 out of 5 by from Great heating as well as low energy consumption 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

Rated 3 out of 5 by from Under desk but 3 feet from furniture?? 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".

Rated 5 out of 5 by from NewAir AH-400 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.

Rated 5 out of 5 by from Great little heater I got this heater for the bedroom, I live off-grid with solar power and don't want to deplete my batteries at night and also not use propane for heating as that is so expensive. This little heater does a good job, it does not make the room toasty, but comfortable and it does not depleate the batteries too bad. I keep it on during the evening, but turn it off when I go to sleep. Very happy with the product and also dealing with Air and Water. Super fast shipping and easy transaction.

Rated 5 out of 5 by from Won't blow my fuses! The fuses in my apt building blow pretty easy. This one has a low enough power draw that it's no problem---keep in mind that this means it's only suitable for really small areas. I use it to warm up the bathtub overnight so I don't freeze in the shower (remove heater before showering obviously). The only downside is the feet, as others have noted. I didn't trust them. They're just too flimsy and seemed like they would melt. I replaced them first thing with some scrapwood and four T-brackets, after bending the top of the Ts upward in a vise to hold the heater and screwed the long part of the T into the wood. I ordered the slightly damaged open box version when it was available and the damage was barely noticeable---a real bargain!

Rated 5 out of 5 by from Safe space heater 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.

Rated 5 out of 5 by from Reliable and sturdy - won't trip the circuit breaker This heater is great because it is affordable, uses low wattage (efficient), and effective. This is my second heater. I bought one now for the office.
