Short version: takes a little while to get used to the way in which the backpack is designed and to figure out the best ways to use it without everything just falling out.Pros:- Anti-theft lock. Very much so needed and it's a very nice snap-in design that is hassle free, I found myself often snapping in the zippers just so I can have peace of mind that it won't open as I'm walking.- Pouch pocket. The pocket on the outside of the backpack is very convenient for just tossing in my keys or phone and I really loved the placement- Strap Pockets. I have another backpack with these too and its just great for easy access to a couple credit cards or even chapstick- Charger port!!! Always a plusCons:Biggest con for me was just the fact that the zippers go all the way down on the sides, because when I'm trying to just quickly grab something while holding the backpack, it's easy for the entire pack to unzip further and cause things to fall out.I get the design they were going for, but execution could've been better. Maybe if a brief "user guide" tag came with the backpack, that'd be really helpful just to understand what functionality the backpack was designed for. Compartments inside the backpack could've been designed better as well, but again I think a user manual would be cool!This backpack by UdoGifts is amazing! I have been using this for the past month as my work backpack. I am able to easily fit my 15" macbook pro with plenty of more space. I occasionally bring my gym clothes and shoes and they fit nicely inside with a lot of room left! I have used this to travel and the TSA approved lock works very nicely. It fits well on top of a suitcase with its subtle strap to allow for easy mounting. The backpack is for the most part weather resistant. I would definitely recommend this to anyone interested in a sleek backpack with lots of utility! Looking forward to more products from UdoGifts!I really liked this backpack because its lightweight and has a lot of room to fit for commute to work. This backpack is Ideal for carrying a laptop and every day travel. The design is sleak and looks very stylish.I got this backpack for my everyday use. It can fit A LOT OF items like my 2001 year model 15.4" Mac Book Pro and its charger, iPad, books, portable power bank for my phone, headphone, and miscellaneous stuff.I also like the color (black), because it is not easy to get dirty. Besides that, the surface material makes it very easy to clean.Highly recommended! Good product!It's a great bag for airports just enough space for a laptop,Portable charger,tablet,all your cords phone maybe a jacket and a pair of headphonesGreat product for the price. I was looking for something that had an external charging port (battery pack not included) for when I walk around town. I love that the design is anti-theft and the main compartment is super roomy. There are more than enough pockets for all my gear and the pack is very lightweight.Very happy that the backpack arrived 2 days after order. The appearance matches the pictures and the quality matches the description. It is actually quite lightweight and a perfect accessory for business casual - very well-designed, elegant appearance with monotone color.I really like the quality of this bag but even the wrap-around info says the bag fits laptops up to 15.6." Unfortunately I tossed the box and it's too late to return it so I'm stuck. I don't think I'll have trouble finding someone who has a smaller laptop and would covet this bag. It really is nice, hence the 5 stars but a great disappointment to me!ETA: I'm downgrading to one star because it's not as described. I wrote the company, thinking that they may have sent the wrong product. Never heard back.
