Unfortunately for the situation I don't have an account on Facebook and will not create it just to communicate with them. But if other people already told them, there is a hope they will fix it.
However, if they don't speak Russian to an extent they do not notice obvious misspellings (like large 'Осторозхно!" instead of "Осторожно!" on a big read placard) it brings the doubts on the quality of the product in general. How did they create a module not being able to even read the manuals properly? I hope this doubts are void, but...
