My Acer V3 772g with 17.3-inch fits perfectly into this bag into it! Convinced Build quality: So I can in the two slots in the cover next to the 3kg heavy laptop still a 10 inch tablet from Acer and additionally carry my old, thick netbook! The front pocket is fitted to the charger, unfortunately full quite quickly. Here, perhaps, the only drawback: The hook and loop fasteners of the front pocket can be just only close if it is not packed ..
That aside, the case protects my technical equipment to my complete satisfaction, a fall would most laptops probably survive: The corners are well padded and look slightly deeper than the laptop, so a buffer zone there.
For the low price at which Amazon sells the product, highly recommended!
