I haven't spend any money but if i had put 550€ to this device i would be very very loud. I think that people who have spent that much money are totally entitled to make their claims without being called little school girls. Its huge amount of money to quite many people :| And its really really understandable that after spending that much of money it´s quite natural to behave not so politely if you are not satisfied.

I do not encourage to behave badly nor i like it, but all I´m saying that ignore bad attitude text and concentrate on problem or try to give help or just ignore.
