A couple of days with unaccustomed Shumka felt a little heavy, but now it's already difficult without it. Put 4, not 5 because of the unpleasant squeak. It is clear that this is not the price segment where you expect a completely flawless assembly, and it’s not a fact that everyone has it, and not just me, but as it is. I’ll hope that it will rub in, well, or I’ll figure out what exactly is rubbing there and try to make some kind of insert from a thin Teflon sheet.
