I turn it on for 7 hours/day (17:00-00:00), on level 1-2. The space I want it to cover is 70 sq.m. The cold is generally broken throughout the space and the temperature improves. Especially within a 2m radius around the stove, the warmth is noticeable. It has wheels and is easily moved, so I move it to where we mainly sit and it is very effective. My gas cylinder lasts 11 days on one level and 9 days on two levels. Installing the cylinder is easy. I am very satisfied.

I bought the stove from a store with gas bottles, and they delivered it assembled and ready with the bottle. The bottle ran out in ten days, probably because I experimented quite a bit with the settings and always kept the living room door open and the window in the adjacent room open. It is the tenth day of the second bottle, but all of last week the stove was burning continuously all day because I was at home due to COVID. It can comfortably heat half the house, that is, 50-60 square meters, while in the room the second time I burn it on setting 1 and with the door half open it heats up to wild (it also had cappuccino weather, of course). I think it smells, but probably from the gas that escapes until it ignites. Out of fear, I always leave the balcony door open at night after I turn off the stove, but that’s my own hang-up. With the bottle at 25 euros, and if I need to change it 3 times a month, which I don’t think will be necessary, it still comes out much cheaper than the radiator I was using until now and which I sold a kidney to pay for the electricity. Regarding the smell, if it doesn’t release too much gas until it ignites, I consider that it doesn’t smell particularly. Note that the frames are old from a neoclassical building from the '50s, but it still heats up.

Owner here for a month. I bought it from the official representative, Smartgas. Excellent store. Excellent service. They delivered it to me in 2 days. The device weighs 12 kg, but the bottom of the packaging is not very sturdy - be careful not to slip from underneath.
The stove itself is of very good quality, sturdy. The wheels attach very easily. No "hammer" is needed. The wheels attach with your hand!!
The device comes with a 0.5 m hose, two clamps, and a regulator from Mondial. These accessories are located behind the protective plate of the bottle, which (the plate), due to transportation, is stuck inside, behind. The stove is very easy to assemble. As for the "leak test," I bought this from Amazon - "TopTes PT199" - a detection device. No "soap" or similar primitive things.
I chose the simple, red Coral Gas bottle. Not the Prime. Because if I got the Prime, I would be bound by its regulator. While with the Mondial regulator it has inside, everything is universal. And I can easily change bottles from different suppliers. The Mondial regulator also works for propane.
The stove does NOT smell... AT ALL, NOTHING. The secret is how you light it and how much you open the valve of the bottle WHEN you light it. I only open the valve of the bottle 2/3 of the way. The stove's ignition button is not left pressed continuously - you press it for 3-4 seconds - then press the ignition button. Try again. Also, do not press the button for opening the stove (with the star) all the way down - it releases gas with high pressure, which causes an unstable pilot flame.
If you leave the stove's opening button pressed continuously, unburned gas comes out into the room until it ignites, and then it smells like unburned gas for hours inside. The "trick" is to press it and immediately get a flame. Then, NOTHING smells. When it ignites, check how high the pilot flame is and what color it has. Usually, you need to slightly close the bottle further to reduce the pressure.
The stove has a logic of "1 ---3---2" with its switch. Some wrote that this is "illogical." It is not. It is logical - you light it on one... if you want quick heat, after 10 minutes, you move it to the maximum, which is "3". In "3";; ...it heats up much faster and with less consumption. After 10-15 minutes, you choose either 1 or 2. It's simple.
The device produces incredible heat, tremendous heat. In position 1, you can easily heat 35-45 sqm with minimal consumption. It emits heat from the front slits as if it has a fan inside - it's unbelievable.
I hope it lasts... You get what you pay for.
Attention - these stoves, up to 4200W, only work with regulators up to 30 mbar - either a fixed regulator or an adjustable one, for example, GOK EN61V50. DO NOT use a 50 mbar regulator for grills!!

I bought it a week ago....
Positive:
1) It has a nice color, it's not like the old classic ones.
2) It is easily portable.

Negative:
1) It heats up the room quickly, for example, a living room of 20 to 25 square meters, but only on the 2nd setting if it's very cold.
2) It has a smell and you can't close the door in a room... It irritates the eyes and makes you dizzy... The space needs to be ventilated!
3) It is relatively economical, but it depends on how often you turn it on. Due to work, I only turn it on at night

As a stove, it is good. I don't have experience with any other, but I am satisfied. The three stars are for the reason that when I needed help, I couldn't find anyone in Greece as a representative to have some small support. I contacted the manufacturer by email and still didn't get a response. This simply means that in case of any damage or problem, I can only throw it away.

Although my experience with gas stoves was nonexistent, I quickly learned how to light, extinguish, and adjust the intensity of it. I would say it's the best purchase I've made for heating my space. Amazing and beautiful. My bottle lasted about a month using only one burner and with daily use during office hours, excluding weekends. Because some mentioned that it smells, I didn't notice anything similar without being the best hound.
