The protective cover corresponds in design and execution fully to my expectations. The smell is on the reviews of other users as much as feared and also acceptable without airing. The dimensions: The bag has external dimensions approximately 345x258x25mm, internal dimensions according to Amazon specification 325x240x20mm. The Lenovo U330 Touch Ultrabook 13.3 inches (322x224x19mm) has enough space. The length of the sleeve 325mm fits very well, the width of 240mm and thickness 20mm could be less a trace, then the protective cover would sit more compact.
