Review on Kitfort CT-3012, 400 W, silver/black by Ada Dymowska ᠌

According to the description and information on the box, the capacity of the bowl is 2.5 liters. However, in fact it turned out that the volume of the bowl is 2.25 liters (measured with a measuring stick). Why? For me this is critical. Asked a question to the manufacturer (kitfort. Ru). They did not believe it, they asked to send a video of the measurement. I sent. Now they are silent, do not answer, but they have not changed the information about the volume of the bowl - crooks. Addendum: still won't turn on.
