The right device, the current values \u200b\u200bdisplay correctly. The outer packaging and instructions look fresh, but the inner one, directly on the device, is terribly greasy. I don’t know where all this was stored, but minus two stars for aesthetics. Another one can be removed for the backlash of the mechanism, but it is not quite small, not critical. But, nevertheless, I note that it is somewhat unpleasant to receive, as it were, a new product in this form.
