The track was not tracked. It came in less than a month. Delivery by courier. After unpacking, the form was restored almost completely in a few days, it was necessary to partially soak and dry several squares. If you are completely picky-2 squares of 8 cut a little uneven. The smell was small, it seemed to fade. It seems that these products (or products of this type and size) are themselves ineffective, and for a noticeable effect, they probably need to glue almost the entire room with a ceiling. I will experiment further. Thank you to the seller.
