When the CBO first started, my previous Rubik was already nine years old, and it had already started to increase in price and became harder to find in stores. As a result, we came to the conclusion that we should get a new one while we still had the chance and dispatch the retiree to the dacha. After taking into account the products of other manufacturers, I came to the conclusion that the Koreans are smarter, and this one makes more brushes. It is possible to set up a timetable, which was not the case with its predecessor (which was some kind of 6 series). It makes a lot of noise and crawls around when everyone else is at work, which is quite convenient for me. The purchase has been completed successfully.
