The cut proof idea is nice for mental security of your bag, while having big enough rings to lock your stuff up.

This a great product and I just got back from a 4 day trip up north. I took my Microsoft laptop and it fit perfectly. Good material. The only thing I wish they would do for the next one would be to reinforce their stitching. Other than that this bag was great. May even buy another one.

So far this has worked very well. Took this to Paris, and it did exactly what I wanted it to do. It's comfortable and compact, light and so far seems very durable. Extremely secure and safe. It is a great looking bag. I would like a waist strap on this bag, but being the small bag it is, it's actually fine without one.

Very impressed with my new backpack. Love the anti-theft design. The external power USB slot is a great feature, haven't used it yet but I like the idea. The backpack is roomy with plenty of pockets and slots for everything, I like how securely it holds my laptop. A pocket for the power brick would be nice, I used the tablet pocket which worked, but isn't optimal. My only very minor criticism is there is no place that will securely hold a pen upright.

I bought this for a trip to Europe. The backpack is highly durable and very comfortable to wear.
