Είχα πάρει 2, τα δούλεψα αρκετά με μικρά παιδιά και πλέον τα έχω εφεδρεία. Τα έχω δουλέψει και σε γνωστούς, φίλους σε μεγαλύτερους χώρους και όλοι έχουν μείνει ευχαριστημένοι. Θέλουν αρκετή ώρα (προσωπικά ανεβοκατεβάζω θερμοκρασία μόνο) για να ζεστάνουν, αλλά καίνε λογικά και κάνουν πολύ ευχάριστη ατμόσφαιρα.

It made no difference in temperature, it would barely increase by 2 degrees after hours of use. The electricity bill was equally discouraging, especially considering that I was away from home most of the time. Additionally, the power button on the side broke within the first month. Bad choice

Return to the store within 24 hours.
It does nothing, neither in 15 nor in 10 square meters. The only good thing is the digital indicators and the remote control.
The legs, however, are unacceptable.
I don't know if any other 2500W heater does the job, but with this one, don't expect to get warm.

It was initially placed in the living room (20sqm) as an additional heating source, as the house does not have good insulation. During the extremely cold weather (January 2017), it made almost no difference (+2 degrees Celsius) and had a slight smell during the first use (which is understandable), but no smell afterwards. Then, it was placed in a bedroom (12sqm) and still had no effect. I returned it.

P.S. a) The house (a detached house) is poorly insulated with cement walls.
b) The cold weather was unbelievable outside (Larissa), with recorded temperatures of -16 degrees Celsius.
*The conclusions are up to you

I am very satisfied. I have placed it in the bedroom next to the bed. It heats up the space immediately and you can feel the warmth it emits. It is quiet, has a remote control, a thermostat, and you can adjust the temperature exactly as you want. It also has a timer. 2 intensity levels. Low and High. In High, it automatically shuts off when it reaches the temperature you have set. While in Low, it does not. However, I believe it is due to poor insulation of the room. I recommend it for a space up to 20 square meters.

Cute design, completely silent and odorless. Very practical that it has a timer and remote control. I use it on the 6th floor terrace and within a few minutes, on low intensity, it heats up the space - 15 sqm - very satisfactorily. In half an hour from 14 degrees, the temperature rises to 20. It is thin enough so that in the summer you can unscrew its wheels, wrap it in bubble wrap, and store it in a closet.

I bought it because it was on sale for 69€. In a 30sqm space, running continuously for 4-5 hours at 2000w, it does something. In smaller spaces up to 15-20 sqm, it may perform better. Overall, I am not satisfied compared to a 2000w halogen in the same space, the halogen is much better.

The smell when heated is particularly annoying.
The door of the room should be open.
The heat for a 15 square meter room is moderate.
Unfortunately, I put it on the shelf after I paid for it.
