When I was looking for a backpack for my laptop, I chose this one. A priori it seemed better than all other options. In my case it is for a Lenovo Legion 5 17ACH6H laptop, so 17 inches, dimensions (W x D x H) 398.6 x 290 x 24.3-26.2 mm. Well, despite the fact that it claims a 17" laptop will fit easily, mine is spot on in the specific area the laptop needs to fit in, but so fair that to insert the USB from the Bluetooth the mouse has to be removed because it wouldn't fit. So tight that the zipper closes tight, tight. The good thing is that due to its shape there is enough space for other things, charger, mouse, etc. The bad or what could be improved: 1.- The interior color, the light blue, could be replaced with a more discreet one. 2.- The inner material looks and feels plasticky, it almost looks like a garbage bag, another better quality material would work very well. 3.- The back handles and top handle look poor quality, and where they are attached to the backpack itself it doesn't seem to last long. 4.- It is not comfortable to carry it on your back, the weight of the laptop is clearly noticeable. It is not advisable to walk with it for more than half an hour. 5.- Too many useless pockets, which also make the product more expensive, increasing the weight and volume. 3 outside pockets (two side and one middle pocket) and up to 8 inside pockets as well as a compartment for pens. Additionally, some of them have a fake transparent nonsense grid that doesn't match anything. The good that would remain: 1.- The exterior color is ideal, best for a discreet backpack. 2.- The upper looks and feels of very good quality. I haven't tested the water resistance but based on other comments with videos I take it for granted. 3.- The zipper, which looks pretty good, also allows you to open almost the entire backpack. 4.- The interior is ideal even with the laptop, neither much nor little. 5.- The detail of the extender to charge a mobile phone can be very useful. In short, I recommend buying this product, especially if the bad things mentioned don't bother you and wait for the handles to hold without problems.
