Office Winter has met its match!
Item Package Quantity: 1
Ok, so this is a rare 5 star review. Got this for my better half for her desk at her office. If you are familiar with “Office Winter” you will understand why. Her office gets freezing cold, people complain, I’ve even been chilled a couple times. This little heater is magic for her. It has been going strong for about a year now, and has given zero issues. No moving parts, so there is nothing to break, just a nice, adjustable, radiant heat that even slightly warms her desktop from underneath so her hands are not completely frozen when typing. The other women in the office have been impressed, and maybe a little envious. So long story short, I have not heard even a murmur of a complaint about this little heater. Office Winter has finally met its match. ... show more

Silent and surprisingly effective, even on the default settings
Item Package Quantity: 1
I have been pleasantly surprised by how much warmth this provides under my desk. My feet and legs are not cold even on the lowest setting, and even when I have a skirt on. I love that it has an auto-off feature, and it's nice that you can adjust all the settings for time and temp, but honestly, the default setting has been doing a wonderful job for me without fussing with anything else. I also like that it's silent. There is nothing to indicate when the heater is on or off audibly. It was super easy to set up, and although I was worried about how long it would continue standing up, so far it's been going a month without falling over. There are supports to add to the corners that help. It IS a bit bigger than other normal space heaters, but I don't notice it under the desk in the office (I have a cube) and no one else seems to have noticed it either (perhaps the cleaning crew, but no one has said anything!). I can't say enough how well this works. Highly recommend. I even bought it on the "discounted" program because I guess someone else returned it, and I haven't had one problem with it at all. Works perfectly. ... show more

Great for Employees in a Cold Office
Item Package Quantity: 1
Works great for employees to use under the desks. Much more efficient than a traditional space heater and feels safer.

Great but Minus 1 Star for the Chemical Odor when it is on
Item Package Quantity: 1
Minus 1 star for the odor. I have had it about a week now. Use it daily and still has an odor only once it heats up and not if it is turned off. It warms well if you use a blanket with it to hold the heat in. I think it wouldn't be as great if I hadn't thought to cover it and my knees both with a small lap blanket to keep the odor down. I drape the blanket over the entire unit and across my lap, like a tent and slide my feet and legs underneath the blanket up to the warming unit. I turn it on every day when I leave for lunch and leave the blanket off of it so the odor can "burn off" and still it has such a strong odor, I can't use it for more than 20 minutes at a time/without the blanket. It does get pretty warm under the blanket and I do feel like it is a good item, if I could just tamp down the odor! It is a strong chemical smell that burns my throat by the end of the day. I don't think it would work very well if your office stays cold all year round though and you are in a skirt. I wear pants so my legs are already partially covered. The cord is also not very long so keep that in mind when you purchase ... show more

First off, the panel works great. I work in a basement office in Minnesota and this coupled with a wall panel heater got me through the winter. Still not as effective as a space heater, but it’s quiet and doesn’t dry out the room. The reason for 3 stars is evident in the photos. The first photo is when it was delivered on Jan 17 and the second photo is from Feb 26, a little more than a month later. It’s curling in on itself and makes me wonder how long I’ll own it before I have to replace it. It still works well, but for $65 I would expect something more durable. If cosmetic value doesn’t bother you then this is a great option, if it does then you probably want to keep looking. ... show more

Keep those legs warm!

My wife gets cold. She works in our downstairs family room, and gets cold sitting and working. It fits the space, wasn’t expensive, and heats up extremely fast. Great product!
