Last winter take stock: heater heater (that's its purpose) but I do not find it exceptionally. Let me explain, I read on several occasions that it was imperative to put his sock on pain of burning with (style it reaches 45-50 ° C), well or I am not very sensitive heat, or I have not been able to work properly but I never had the feeling of burn me even without the sock.
Moreover, it must wait until it is easily functioned for 1 / 2h for this heater is in the heat (without boiling).
In summary, this is not what I expected (lower heating my expectations), I continued to use it but if the purchase was again I would not do (but I repeat after I have perhaps failed to work properly).
