The bag is designed for 13.3-inch notebook, is made of neoprene and is processed perfectly.
Actually, I have no reason to complain about, so why "only" 4 stars?
Simply because my laptop (Lenovo Yoga 2 13.3 inches) in has too much space.
It could have been a little more closely ...
Nevertheless, I see this as no reason for complaint, I can live with it and one or the other might like that also have very happy, after all, makes the space even to mouse / HDD / charger should grab.
I myself do not like something, I transport these little things always separately.
Conclusion: Good pocket for small money, well made, but unfortunately a little too spacious for my taste.
