Very good quality in zipper and fabric, seems durable
The wheels roll just fine and I didn't encounter any problems (in response to a comment I saw)
It doesn't have a handle to pull it
The straps are relatively comfortable

The only negative is that the opening from the top is relatively small so you have access to the inside of the bag
Also, it doesn't have side pockets, it only has one small one in the front

Enough space for army stuff. The only negative thing is the wheels. You can't keep it straight for anything. This may be due to the fact that it doesn't have a handle to pull it and you hold it from the handle, but still.
