Newair 400W Portable Under Desk Heater - Slim Fit Design with Silent, Energy-Efficient Operation, Ideal for Office, Desk, Home, and More

I was nervous about purchasing this heater after reading the reviews. Here's what I've learned after taking a chance.1) To attach the feet, press them in the MIDDLE, not on the sides. And be gentle. I had zero issues.2) No tripping the circuit breaker at 400 watts!3) Based on the Min/Max setting you set the heater to, it will heat up, then cut off, then cut on again at regular intervals. This means you get the heat level you want but also that the unit won't overheat (though, if that happens, it has an auto cut-off). When it cycles off, you'll hear a click. Same thing when it cuts back on—just like with an HVAC wall thermostat.4) The cord is longer than expected, which is great because it means I didn't need an extension cord. But if you DO need one, the product booklet that comes in the packaging specifies which rating of extension cord to use.5) While the heater is in operation, there is no noise at all.6) Even at a little above "Min," it puts out a decent amount of heat, so if you're using it in a small space, you'll be fine.I don't expect this heater to last forever, but I registered it anyway. If there's ever an issue, the company looks to stand behind it.

I wanted something slim to keep in my upstairs bathroom and something that did not draw alot of power. This unit is quite slim and 400 watts max. There's a dial so I guess if you turned it halfway you'd be using 200 watts approx. Heats up quickly and silently and quite does the job in my 7x5 bathroom. You are not supposed to get it wet- it says on the box don't use it in the bathroom. But use some common sense and don't splash it, don't keep it too close to the sink, and turn it off n move it away from the shower before showering. It makes no noise at all while it is warming up or maintaining heat. The only noises it makes are when you turn it off. Then it makes some decently loud clicks every couple of minutes for about 10 or 15 minutes. No big deal. Would be nice if there was another handle on it so you could pick it up with two hands to move it. Some have complained about the legs not being sturdy. I had a little bit of difficulty getting the legs to snap on as they should, but did triumph in the end, and it is quite sturdy. Would recommend for other small rooms or as a personal heater... next to bed, next to couch, etc. Very nice, very happy with purchase.UPDATE 2/8/2018. Still working well for my bathroom. Helps out a lot before getting in the shower in the morning, as I turn the heat down to 68 at night. My bathroom, and the rest of my upstairs is like 60 degrees on a cold morning (upstairs 60, downstairs 68- bad insulation I guess) and this little heater does a great job of quickly getting my bathroom close to 70 by the time I get in the shower. Also, tho I don't take HOT showers, this heater also keeps the mirror from fogging up, and I lay my semi-wet towel across it when I finish drying off (turning off the heater and not covering the vent.) Does a nice job too of warming my socks up when I get home from work.Update: 10/22/14...... I have recommended this heater to a few people. It's a shame there are a few bad reviews here JUST due to some of the heater's feet. Some older models had plastic feet and this caused issues with breaking legs and instability. Mine are metal, and have caused me no issues whatsoever- never had to re-adjust the feet. If you are on the fence about buying it, don't be.Update 1/13/2016......Ordered another one for my drafty kitchen for mealtime. Checked the feet on both units- I am pretty sure they ARE plastic! Magnets slide right off. My apologies to those I may have offended. Sounds and feels like metal when you tap it. Very strong though, and I have had zero issues with it. I guess a few people got duds.

So far, I think this heater has the potential to be a winning product — except for its one major flaw, noted by many other customers — the tendency for it to melt its plastic feet, fall over and be useless and potentially dangerous.I bought this product KNOWING about this serious flaw. Why? Because I needed a heater to put into a compact space (under a porch to keep pipes from freezing), and after a LOT of looking, I couldn't find ANY small space heater on Amazon that didn't have reviews of people warning, "This is dangerous, and may burn your house down!"The selling points on this heater were its enclosed oil-filled nature, and the fact that out of 1,187 reviews (as of January 2025), I only noted one review that said, "This heater exploded." All of the other reviews were of people warning that it would melt its factory-supplied plastic feet.Well, that was a fixable problem.So I ordered the heater. Once it arrived, I put the plastic feet on and fired it up. I wanted to see whether I felt it was necessary to make my own. And after a little bit, it got hot enough that I thought, "Yeah, I'd better do this."The bracket was a spare piece I had in the garage, that I cut into four sections. I attached two pieces per foot with a screw and some washers, including a lock washer. Then I cut a couple of feet from a spare 1x4 and screwed it on. Done!I made the feet wider, and I used as much of the bracket as I had available. The piece I started with was 13", and it cut nicely into four 3 inch sections. Having some extra metal down there helps dissipate the heat before it gets to the wood. It's still hot — when it really heats up, on the hotter bracket I have to remove my hand after a few seconds — but it shouldn't get hot enough to cause any kind of fire concern.Even so, I'm going to provide a smoke detector in the room, and a fire extinguisher. It's cheap insurance in a situation where, realistically, it's not going to be monitored all the time and will most kick on at night.Now, just as long as it doesn't develop an oil leak (which is a problem a few other customers have noted), we should be good to go.
