Always excellent these products Amazon Basics! And for a price almost two times lower than the market leader with almost equal quality! I can accommodate a laptop of 11.6 "(30.2 x 20.1 x 3.0), but there are no rab !!! I can say that if I let the transmitter of the wireless mouse, it takes me . be careful when returning it in the bag not to hook the inner flank But by slightly pulling on the hanging ring, it goes very well FYI, my dongle exceeds 7.5 mm Hint:.. I rounding the sharp corners of the plastic cap of this little accessory. Thus, there is less risk of catching the seams of the interior trim. The main compartment can accommodate a computer so (it is the goal; o)) and a large notebook (21 x 29.7) a hundred pages or magazine (no more ...). On each side, there is a bag (17 x 25) which can accommodate a small notebook. In my case, I go without forcing a large and a small notebook in addition to the PC, or 5 reviews 140 pages (without the PC, but it's for example!). The small compartment can accommodate a book of 18 x 24 and 250 pages max. Preference is, I think, will place the accessories. There for it 2 small pockets sewn without gusset (an 8 and a 9 cm). Only the largest allows me to accommodate an external hard drive 2.5 "(109 x 83 x 17 mm). The other is too small for that. I would have preferred bellows pockets and / or elasticized. I can also put at this point, my mouse lumberjack, a desktop model what! But there is not much room! Thick 4.0 cm, it will fit in any pocket ..... I therefore instead on an edge since the pocket center contains the DD 2.5 ". This gives a rather potbellied appearance in this bag (say within 8 months pregnant; o))! There are also 2 slots for pens. Difficult to accommodate the charger .... but .... it fits by forcing a little! O ((Pas glop! A third compartment at the front, with a small (!) Zipper opening, accept wire and cable (USB, HDMI, etc.), the charger (if it is not too thick), phones, etc ... But why then have reduced the opening? ..... To earn a few cents on a smaller zipper? The opening is 17 cm while the compartment is 14 x 24 cm! I would have liked easier access. With Zip greater, Velcro or magnetic flap ?? Too bad. But we must recognize that the chosen solution will make falling more difficult objects. Consider it as a good point! Adjustable shoulder strap of 1.35 m long with a swivel at each end and a full asymmetrical padded shoulder the whole. Well done all! Long enough to fit all body, it even allows the cross port. A flawless finish, like all objects of the series that I had on hand. Rather elegant and inexpensive ... what more? We do not hesitate ... Finally, I said that I was able to go without belabour or annoy me, the computer mentioned above, with charger, HDD 2.5 "and 3.0 USB cable, HDMI cable, an audio cable Jack 3.5 to 3 m, a USB 2.0 cable 1.20 m, my big mouse and dongle .... and a large and a small book of 100 pages each! That's right, and there's more place for toothbrush ... but it takes!
