    The order was made on 26.02.19, came to chelyabinsk on 11.05.19. The slowest delivery in all years! The store even extended the protection, immediately for 2 months, apparently already in experience. The goods have not yet checked, other things are full, not before already) for super slow delivery 4 *, and since the goods as in the picture.
