Della Gao Laptop Backpack, Business Backpack Bag with USB Charging Port,Water Resistant School Rucksack for Men Women for 15.6-17 Inch Laptop and Notebook for Travel,College,Office-Black

I have this backpack for a few days. Generally, I used it when I go to the university. I bring only first part of the backpack when I have to bring just a laptop and a few notebooks. I add the second part when I go to the gym. For me, I can put it laptop and things for the gym but don't expect to put too much.I have laptop acer predator helios 300.

the bag definitely has a creative design but the quality of the material is compromised. The bag will not last for even 6 months.

I have mine for almost 5 months now and this is a fantastic backpack. External USB and 3.5mm jack works good (even the sound is not that good). The extensions are fantastic but unfortunately you can not buy those separated.

Fits my Entroware 17" laptop perfectly, and is still comfortable carrying that and all its peripherals.

Very nice
