This is a simple and great heater.

Guillermo February 19, 2021

This is a very simple heater. It has three heating rods which use 500 WPH, each. You have three settings. The heating and consumption is 1, at 0.5 Kwh, 2, at 1.0 kwh, and 3, at 1.5 kWh. It has no fan. The closer you get, the hotter it is. However, using a ceiling fan directed upward for winter, it distributes the heat well in the room. When the temperature gets below 50 f, I use two in the 14 by 18 living room, one at each end. One is set at 1.5 kwh and the other, at .5. by the point the temperature is below 45, I set one at 1.5 and the other at 1.0.

Could be Better

Michael January 19, 2021

This heater does not have a fan to help move air past the quartz heating elements like some of the other quartz infrared space heaters. Although it might be by design, it makes the heater seem to not be very warm at all unless you stand in front of it. It is very quiet because there is no fan. I guess this is a good space heater if you are looking for something quite. If there was a fan to help move are it would be a good choice for warming cold basements.

Unsafe

Laurel March 13, 2021

This heater almost caught my house on fire. It does not have a safety turn off and ended up blowing out my outlet. You cannot fully turn off this heater without unplugging it. If you leave it plugged in, it stays on even though it appears to be turned off. This heater is not worth the money and is completely unsafe

Best to be used when you are not moving around

gatobarb December 18, 2020

This one doesn't has fan or blower to blow the heat to the whole room. But it is quiet, has no noise out. And it puts the heat directly to its front. So it is very good to be used at home office. I sit in front of it, then it keeps me warm. Although it takes long time to heat the whole room, it heats my body fast. And if you are in an open space at home, you get warm from this heater better than other space heater because you receive the heat directly and no waste of the energy.

Wonderful, cozy, aesthetic portable heater!

Mommyto6 December 3, 2020

This is a wonderful heater! We actually saw a local restaurant using this heater for patio dining to keep customers warm along with patio heaters due to indoor dining restrictions. It not only looks nice, it gives significant heat even on the lowest setting! Its light and easily portable from room to room. We also plan to bring it on our patio when we do sit outside on chilly nights. The price is really reasonable! I definitely it hope it lasts a few winters!

The Best Heaters Ever!!!

Tempie January 10, 2021

Oh My Gish! I'm soooo in love with these heaters. I have bought two and thinking about going to get another one. The run so smooth, you don't even know that they are on. The heat is pretty good too. It keeps the rooms warm and toasty like I want. Since they have three controls for the amount of heat, I adjust as needed. It's the quietness that I'm in love with.

GOOD Space Heater

Presela February 18, 2021

This is a very good space heater for use in a living room or bedroom. It heats very well and has 3 settings. With the freezing weather here in Texas this week it has been a Godsend. I have had it near my sofa and it has helped keep me warm in that area. It is radiant heat and gets very hot on the high setting. It does not have a fan but I prefer no fan when it is this cold. I would purchase this item again, may get another one for next winter.

Awesome heater!

Jade February 13, 2021

I love this heater! It's so perfect for a small area. I use it on my patio and it's perfect! It's great for a personal up close heater. I also use it in my office, which is 8x12 and it's always nice and toasty. Will it warm a bigger room, no, but it's worth it. I have a wall in my office that is just windows and keeps me so warm. I've already had some friends buy one and they love it too! Get it!

1 star

Christopher November 3, 2021

Heater worked great for 1 winter. Really heats up a nice sized room in a short while but cant warm up an entire house by itself. Tried to use it for a second winter it started shorting out trying to shoot sparks. So it actually only worked for about 3 months then threatens to set my house on fire while Im asleep. I wouldnt recommend its a dangerous and unreliable product from my experience.
