I want to leave an update. This week one of my cats became very ill and the weather here during nights has been cold. I had to separate my cat in a smaller room where he could be comfortable, rest and heal while I kept an eye on him. This little heater kept that small room comfortably warm for him on the min setting/ #2 all night and day.
To some this may seem like not a big deal but for me it was very important to keep my cat warm and comfortable while his little body healed from the sickness he had. This little heater is still in that small room, because like I've mentioned before it is the laundry room and is on an outside wall that gets very cold in winter (the last thing I need is frozen pipes that break).
I'm very happy to have bought this heater in time for colder weather and also happy that it has done such a great job in warming the area that it is kept in. During the nights with the wash room door closed the room was very warm and comfortable. On the nights and days of leaving the washing room door open the entire den attached was also kept mildly comfortable and warm (which is amazing because it is large with concrete floors and no carpeting, plus a skylight).
I cannot recommend this heater enough. It is a great find and was quiet enough not to make noise that would scare my cat while he rested and healed (he is doing much better now and is healing).

Initially, I did not like this unit at all based on leaving it running overnight on high and not feeling warmth in a medium-sized room.
What changed my opinion? I gave this heater a second chance and was amazed at just how much warmth actually does come out of it.
My grandmother used to have a larger radiator heater of this brand and loved it. That heater would warm up the living room (a medium-sized room) perfectly in winter, so when I saw this one I knew it was a must for our home. Earlier this month the central heating/air conditioning unit went out and is unrepairable, which has left us in a 1250 sq ft (appx 70-year-old) home with no heater. My house was weatherized last year by the utility company & I have put up thermal curtains in all the rooms, laid down rolled up blankets against the bottom of doors leading outside and since my home has hardwood/cement floors I've added small area rugs in most of the rooms to help keep in the warmth.
This is the first winter in 22 years that we have no central heat and I admit, at first thought, I panicked about how to keep this house warm during winter.
I've done my research on zone heating & know that space heaters can/will & do raise the electric bill in winter (my gas bill with the central heating unit was always right under $200 a month during the cold months) so I am hoping to at least save a bit on heating this way, as there is no other option for us this winter.
I have a small space heater in every room we spend our days or nights in and they do manage to keep the house warm when it is freezing outside (we have already had freezing temps this year).
This little heater might be small, compact and quiet (no fan) but don't that fool you. The amount of heat that actually radiates from this heater is enough to literally warm to comfort a medium size room (if left on day and night during a cold spell).
The very little noise I do hear from this heater is clicking or pinging when it is heating up and then there is silence.
I have it set on the lowest temp during the day and then raise that up at night when it is the coldest (I do not use the green button for saving the heat setting to the room temperature). This heater stays on all day and night when it is severely cold in my washing room because of the room being so small & having a single pane window (not a regular storm window like the rest of the house). The washroom gets very cold (cement floors with linoleum) and I fear the pipes for the washing machine will bust with the severe cold air, plus that is where the cats' litter boxes are. My cats have warm butts when it is cold at least.
What I thought is the radiator heater would warm up just the small washing room and not the den attached to it, which is the largest room in the house, but on high setting, this heater warms up both spaces nicely.
I've attached pictures of the heater on the lowest setting #2, which goes up to 6 and has a min/max button plus the eco setting (the large round button that turns green when it is on). The warm air comes out of little vents on top of the unit and radiates from the middle & back of the unit. Use caution because once this heater is fully warm the back part (has no handle) and gets very warm (enough to burn someone & actually hurt). The rollers are attached and fold under the unit for storage. This is a lightweight heater and can be easily carried from one room to another, if not rolled. Since it is a radiator, there is no fan that kicks on and off throughout the night to keep you awake if you choose to keep it in a bedroom. And when you need to store the unit on the bottom front there is a place to wrap the cord back up so it is safely out of the way. One thing I always forget to mention is this has a 2 prong plugin, instead of a 3 so you don't need an adapter to plug into the wall. The electrician that came to look at the central heat unit said that space heaters are safe if you don't drape anything over or around them and do not plug them into anything but an outlet dedicated to that one heater (no smart outlets, power strips, surge protectors or the like) and always leave space around the heater so it can breathe properly.
Just a couple tips for winter:
Weatherize your home (sometimes the utility companies offer it for free to homeowners)
Put down rolled up blankets or towels along the bottom of doorways to help seal out the drafts that can come in.
Replace curtains & mini blinds with thermal backed curtains that not only help seal the warmth in but also keep out drafts and noise from outside. Make sure the thermal curtain hangs at least 2 extra feet below the window frame to help prevent drafts or cold air from coming in through a window (especially picture windows found in older homes).
You can also roll up a towel and place it in between the door and screen door to help prevent drafts on a door not sealed or weatherized.
If you zone heat, place space heaters in a corner of the room away from anything that can catch on fire if the heater gets too hot, but also in the direction of where you want the heat to go. That way the heat will circulate throughout the entire room instead of placing a space heater in the middle of a room where it will only push air from that point forward and leave cold air behind it.
To avoid tripping the breaker box, use the lowest heat setting on a 1500 watt heater and space out the heaters on different circuits around the house (one in each room on a wall with no heavy appliances) and be sure to turn off the space heater if you plan to vacuum or run a device that takes a lot of energy. 70 degrees and below seems to work well in not tripping the breaker box in my home, as anything higher trips the box if I vacuum or use the hairdryer.
Hopefully, these tips help and my review as well. I'm on a budget and thankfully Amazon has some great prices on items that are a must have.

Both heaters arrived quickly and undamaged, but we quickly determined that one of the heaters had a rhythmic clicking about every hour or so. After having the clicking dance wake me up about every hour throughout the night, I called the manufacturer. They said the clicking was not normal and that the unit was defective, and this is where I really like Amazon. I boxed the unit back up, visited the Amazon website, selected UPS pickup right at my door, and two days later the defective unit was on its way back to Amazon with barely any effort on my end and at no cost to me. Simultaneously with the return, I opted for Amazon to send me a replacement unit, which arrived within about three days. No double charge to my credit card since Amazon had my old unit within the allotted 30 days.
As for the units themselves, they work great and are very quiet (just a single very subtle thermostatic "click" every now and again when the unit triggers for heat). My father-in-law bought a fan heater from Lowe's a few days before I got these, but took it back because it was too noisy. My wife told him we ordered oil filled heaters from Amazon and they were quiet. He came down to look at what we got, and ordered his own from Amazon.
The units emit more than enough heat to keep any of our individual bedrooms warm, even with the bedroom door left open. I left my daughter's room closed for a couple hours to warm it up before bedtime, and when we opened the door, it was way too toasty (her room is about 12x12 with an adjoining bathroom that is probably about 7x7). The unit certainly helps larger areas, but don't expect it to heat a 25x25 area up to normal room temperature when outside temps are 30s or 40s. Having said that, I was happily surprised that our 25x25 living room space never got below 65 with just one of these heaters running in a corner. So it will certainly keep any room livable and comfortable.
I gave the unit four stars, but admittedly not giving it five stars was difficult. It is a compact unit sold at a very reasonable cost. It is easy to set up and operate. It is quiet and will keep you warm (but be patient, because it takes a little while to get things warmed up). I didn't give it five stars because, while it is constructed well enough, it's certainly not built bullet proof. The other reason is the unit's very singular and limited role (i.e. it doesn't have options that might make it more versatile). But it's precisely these demerits that undoubtedly provide for the reasonable price, hence my five star dilemma.

UPDATE May 2018:
After using these 2 heaters ALLLL WINTER (24-7 in a cold rural Ontario house)I have to say we LOVE these!! Infact I just ordered another one lol! It’s a good constant heat, they are silent. We only turn both the Min and Max buttons on till it heats up well, then we just leave them with the Min button on, and the dial turned to number 2. I’ve never gone above 2! They make a 12x12 room a HOT after a night with the door closed lol!
I think my electric bill went up maybe 20$- and TOTALLY worth that to have a warm comfy heat that didn’t dry our sinuses and throats out by morning as was the norm here previously.
A good quality item we think. We were expecting a lightweight maybe crap quality but put our faith in reviews on amazon.com. It heats up quickly. rolls well - just fold the wheel down or you'll scratch your floor like us :-/ Compact and tidy looking. Overall a great value for the price and type of heater it is and honestly it heated up my daughters 12 x 12 room in about half an hour from 55F degrees when our furnace bit the dust. We put one in my one daughters room and one in the other bedroom, with my sons room inbetween them- and it kept his room warm too lol! Just tell the kids NO TOUCHIE! lol - They do border on hot to the touch when they get going- so common sense mom's and dad's. Don't put then up against walls and curtains etc.
(And I prefer the NON digital models- I believe it leaves less to get broken or fried without digital parts. A bit old school but who cares)
We are betting that these make a dent in our drafty house in our -35 winter- from their other reviews we think they should continue being effective.
