OPOLAR Space Portable Ceramic Heater, 600 Watt Personal Mini Heater with Smart Infrared Body Sensor, Silent Floor Heater, Over-Heat Protection and Tip-Over Protection, Quick Heat-up for RV Office Desk

This nice little space heater keeps me warm at work, where they refuse to turn of the heat in the winter and they crank up the AC in the summer. I keep it under my desk and I can feel the heat in my whole cube. It doesn't make too much noise to distract me or any coworker. And it shuts off when I step away from my cube. It also shuts off when I don't move after a while, which serves as a good reminder that I should get up and stretch.

It works well. My room is spacious and it does a good job of circulating heat to warm the room up. I live in Philadelphia, and as of this review, our fall season has had morning lows of 38 degrees and daytime highs of 54. This has kept my long bedroom nice and cozy.The safety feature of it shutting off when it tips is nice, but it will shut off whenever you barely move it. First time that happened to me, I thought the product wire was messed up and shorting. Not so (gladly), but it is odd.I don’t use the body-sensor, not interested in that.Overall, 4.5 stars, and would recommend this, especially in kids rooms because of the tip-over shut off feature.

I really don't think I should have expected much for the price, but this was a lot smaller than I had anticipated and unable to use it for the reason I had initiated the purchase so I decided to bring it into work and use it to keep warm in the cold office and it works great for that purpose.

This is a very clever and ingenious heater. The case is very thick and tough, and very well made. I use it under my desk and it’s perfect for the amount of heat it produces in such a small unit. The unique heat sensor gives me confidence in the safety of the unit. The sensor turns the heater on only when it senses a human near it. So, when I leave my desk, it automatically stops running, and turns on only when I’m near. Fantastic!This was the second unit I received after the first proved defective. That can happen with anything bought on the Web. But, Ben in Marketing, proved the company to be responsive. He sent me a new unit when I explained the problem, and he did so immediately, with no hassle. How many other vendors provide the same response?

For a small size it does produce plenty of heat when used to keep feet warm under office desk. However, one big issue with this heater is noise level. Not surprised at this price point that the fan used in this model is cheap with uneven fan blades and whiny motor. I would pay extra for a model with an upgraded fan. Motion detection is an interesting feature however not very useful. Periodic movement is required in order to keep fan running otherwise it will shut off with my feet right in front of it. So not sure about usefulness of this feature.

I bought primarily because my fingers get so cold in my office, this is a GREAT desktop heater for this exact purpose. The only very teeny tiny complaint I have is that to get the heat level with fingers / keyboard I had to turn sideways and make sure the safety button on the bottom stayed pushed in, but that's just preferential. However, it takes the "coldness edge" out of my office without being too overwhelming - def recommend :)

It arrived and did not work. Sent it back and got a refund.

This has turned out to be the perfect little heater for one of my bedrooms! With the door shut it takes a little while to heat up an average size room but than it keeps it warm all night. My only concern was that it didn't turn off immediately when I pushed the power button. Then I received an email from the seller explaining that the fan stays on for a few seconds after turning it off to cool it off, and that is exactly what happens. Very pleased with this little heater!

Amazing how much heat comes out of this little thing. Perfect desktop / table top heater for those cold spots by the window. Love the motion sensor but if you're just sitting there reading it will shut off on you until you move so it wouldn't be good for a bedroom while your sleeping. The auto shut off if it tips seems fail-safe with a button on the bottom that pops out when its not upright. It would be great if one could control the heat output but that's asking a lot for the price considering all the other feature. I just move it a bit further away further away.

I have this seated under my computer desk, which is in a small office (6.5 x 5 ft)Warms up the room nicely, and keeps my body warm when the basement gets cold (the office is located in the basement).I can definitely see this being under-powered if used in a large room, however this is meant for SMALL rooms. If you're purchasing this for a small space, you'll be happy with it.

The warmth it emits is very comfortable, like sitting in front of a fireplace. In fact, it's so comfortable that I sometimes get sleepy while studying when this thing's on! The motion detection does need improvement though. Sometimes it detects me, sometimes not. Also, even when it's running, the heater's body doesn't get hot, which is great if I want to move it around.

I have left it on for 3 days in my bathroom, and it was still running. Motion sensor, heating for 600 W works as described. For a bathroom of size 8ftx8ft, you will have to leave it on for about a couple of hours to make it warm.

Love this portable heater. I use this in my room which get's quite chilly in the fall and winter months.
