Verified purchase - review from a price comparison website
The product arrived damaged + non-functioning driver. The heater functions cannot be used without the controller. This is quite limiting even if the controller goes out after a while of use, the heater becomes just an overpriced decoration

Purchased as a bathroom heater. Quickly heats the bathroom, wide range of settings and programming, great design. I have only the best experience with the Czech brand Concept.
Design, control, efficiency

Too noisy fan - I returned it.
Clear application
Fast heating
The fan speed cannot be controlled. The fan runs at high speed and has only an on/off function. Only the temperature can be controlled.
The product worked for one day and could not be started.

This product contains a manufacturing defect. After starting, characters from various functions that are not active flashed on the display. So I immediately replaced the heater with a new one. With the new one, the situation was repeated, and the remote control did not work. The exchange is no longer possible, so I have been waiting for 2 weeks for the claim to be processed. Definitely can' t recommend!

Defective from the factory, after replacing it with a new one, the situation repeats itself.

It works fine on the 4100 version. Pairing immediately after the first launch without any problems
3 power levels, consumption corresponds (measured). The air temperature at the 2nd stage at the outlet reaches approx. 80°C
Mounting on the wall is no problem
After reaching the temperature, the device cools down and switches off. Which many devices do not do, they usually switch to the air circulation function
Absolutely inappropriately solved temperature sensor. When installed near the ceiling, the measured temperature rises to 50°C within a few minutes
I couldn' t find an option anywhere to keep the display of time and other information active even after turning off the device. (it is possible to turn off the device and then display the information)

Appearance, glass front panel
Inaccurate temperature sensor, shows higher temperature than reality
Not suitable for tempering, the heater turns on for 10 seconds and then cools down for another 10 seconds and turns off again. It is 2°C in the room and the direct heater switches on in 5 minutes.
