The p17 Lenovo for which I bought this specific bag barely fits with a lot of pressure. Other than that, it looks great.

I have it for a very short time but the first impressions are very good, mainly in terms of build quality.
The only complaint is the limited space in the side pockets.

Excellent with plenty of space, good quality construction and materials. Its durability will be shown over time.
Update one year later:
It is used daily to carry a laptop, sometimes I need to carry two due to the nature of my work. In the large compartment, a thermos and a food container fit comfortably. I have loaded it many times to the point where it barely closes, and essentially, with such daily abuse, it is like the first day I bought it.
