The straps go over the laptop's main zipper, so it's practically impossible to be stolen in the metro, etc. although it's a bit difficult to take out the laptop. It doesn't have many small pockets for personal items, but a relatively large one in the front where you can throw them loose. Personally, my neck hurts a bit when I wear it, but maybe it's because I need a smaller bag due to my body type.

Honest bag, does not provide enough protection for the laptop, but with a neoprene sleeve for the laptop, you're okay. It's not for heavy use.... For simple professional use, it's fine. Also, the main zipper doesn't open easily, you have to lift the carrying handles.... you could call it an anti-theft system, it doesn't bother me. For its price (~15 euros), it's great!

Value for money. Quite large and comfortable. It is stated in the description that it fits laptops up to 15'. Mine is 15.6' and it fits comfortably.

The one strap started fraying at the top from the first week, with use only on one shoulder. Not good for so early on.

The construction is very good and the price at €15 is definitely excellent.

The major drawback (and the only one based on my own needs) is that there is no additional compartment (neither for a pen, nor for a protective case for a hard drive, mouse, etc.).
Relatively small bag, it covers anyone who wants to carry a laptop and a few extra things.
Although it states that it is for 15", my own 15.6" laptop fits (barely of course).

Update 2 years after purchase: the bag is like the first day I bought it, despite the fact that it is used daily.

Overall very good. I would like thicker cushions in place of the laptop (all around). Otherwise, for the money, it is very good.

With minimal use due to recent purchase, it appears to be of good quality and definitely safe for the laptop. I think it's value for money!

The bag is awesome. Initially, it is very elegant, especially for a laptop bag, but also compared to other anti-theft bags. When you wear it, you don't feel the laptop on your back and it has space for other things. Additionally, the front pocket is convenient for items you need immediately (quite large).

I was mainly looking for an affordable anti-theft bag that wouldn't get cluttered with things.
I don't use it so much for a laptop, although it has a special compartment for it.
The bag is really reliable for its price, as it is quite good quality for a price of 15-16€, compared to more expensive ones.
