Vysoko kvalitný produkt, ktorý je vhodný napr. vo vnútri voľnej rukavice alebo rukavice. Rýchlo sa zahreje a poskytne príjemné teplo. Sám používam ohrievač pri bicyklovaní asi 15 minút na ceste do práce v mrazivejšom mraze. Slabosťou je, že teplota klesá pomerne rýchlo, asi po 10 minútach používania je to celkom skromné. Avšak pre moje vlastné použitie je produkt v poriadku.

Myslel som si, že horúčava vydrží dlhšie. Varenie trvalo dlho.
