Awesome design and quality. It delivers what it promises, not miracles. If you want to heat a room larger than 30-35 square meters, you will probably need 2. It's worth the money and more.

It is suitable for up to approximately 25 square meters, provided, of course, that the surface has good insulation from the windows.
The fan helps to heat up the space faster.
3 bulbs with the ability to turn on as many as we want.
Thermostat and stop function in case of a fall.
Durable metal, good quality.
The price is a bit steep, but it does a relatively good job!

Very good, almost silent compared to other ones. However, one star less because the thermostat doesn't turn it off completely, meaning one bulb keeps burning continuously

I had two stoves of another brand and they did nothing compared to the GRUPPE stove..and in 10 minutes the room becomes an oven and then you can lower it and leave it with just 2 bulbs!

Satisfied with the stove, it quickly warms up the living room with 2 light bulbs on, you're all set. I lost the paper with the stove instructions and I don't know how the cable goes inside the stove (it's like the electric ones where you pull out the cable from inside).

I have it for 1 year and it comfortably covers a studio apartment of 32 sqm. I live next to the sea and it is ideal for the winter humidity. It has 3 levels-thermostat-fan, I only turn it on at "1" and I am perfectly fine (always in combination with the rugs)! My sister has 2 in Kefalonia and she is equally satisfied! And the most important thing, my electricity bill from the power company came normal...
