Bought the bag for a 15.4 "laptop. And even though the laptop is small, he still is tight in your pocket, thanks to Velcro. Wanted to purposely a larger bag because I wanted to accommodate the power supply still inside. That's why me a parting strip was also very important. Everything else can be accommodated in the outer bag. Zippers are good and not "hook".
The only disadvantage is possibly. This is the handle too close to the bag and you are constantly "ripping" with his hand to his pocket. Neutral I value in this price range of laptop, if one takes the bag, at the bottom is slightly slack.
For this price, I find it good and solid and also looks very good, I think.
