I am using Ozot. Small new company and no complaints with anything.

11-15c is preferred? Yet living in a house with average temp under 18c is harmful to health according to studies and the average recommended temp is 20c according to what I am reading across multiple governments worldwide.

So please, could you cite your source that 'dying of cold' is the preferred temp of humans?

You say it was a reputable store. But you have no license for office and a warning about it being an illegitimate copy installed.

I would be taking it back to the 'legit' store and asking questions.

I have already got this message. Was annoying. But yes it's true. 2 yeses and no stay hidden out of the way in bottom left smallish print.
