Bought this for a trip to Europe as a carry-on bag and daily travel around town. Put it through three weeks of heavy use and now use it for my commute.

The good: The trip gave me a chance to really test out the bag. The construction and materials are pretty durable. The strap is comfortable even with a packed bag. I was able to fit all my electronics and cables needed for the trip with no problems, though the bag did get a bit bulky fully loaded. Using the bottom compartment for power supplies made the bag sit a bit 'lumpy' and uneven. The Velcro sleeve on the back of the bag was great as it perfectly threaded through my carry-on suitcase's extended handle. The zipper feature to split open the bag and lay the laptop compartment flat so it could go into security scanners is a really nice feature and saved me a ton of time repacking the bag at each airport/train screening point.

My bag was delivered with scuffs/slight wear marks already on the green fabric flap, but this was a shipping issue more than anything.

I'm giving it 4 stars due to a few issues that other reviewers have brought up.

1) Center pouch is very small. Once you put a laptop and/or tablet in the back compartment there is really very little space left in the main center pocket for much more than a couple novels.

2) Strap hooks are not very practical. While they look nice, the strap hooks on the front of the bag come undone quite easily if any tension is lost in the strap and are a pain to re-hook when you are rushed. Dangling hooks can also catch on other things- as I found out the hard way. Standard snap claps, as found on the shoulder strap, would have been a better option. Because the hooks come off so easily, I ended up relying on the Velcro strips under the flap to keep the bag secure.

3) Handle is not centered. The handle on the bag is not attached to the center of bag flap, but along the back side of the bag, near the laptop compartment. When the bag is full and you pick it up by the off-center handle, the bag becomes awkward to carry. You are pretty much forced to use the shoulder strap to get the bag to balance properly.

I would recommend this bag, but would like to see the company address these three issues in future versions of the product.
