I am really happy with this purchase.  I am in Nurse Practitioner school and we have lots of books.  Sometimes it isn't large enough to hold everything, but it forces me to be selective.

It is very balanced and easy to roll.  The handle telescopes easily.  The wheels are rubberized a little.  It keeps them from being all clacky on hard surfaces.  They aren't silent, but not ridiculously loud.  I never use it as a back pack and the straps are zipped up.  They never get in the way.

There are two front pockets.  The first one is great for skinnier items and has a top pouch inside.  It holds my Kindle Fire prefectly.  The other front pocket holds all the random crap a student needs handy.  It unzips fully, but has fabric on the sides.  It keeps it from flopping open completely and dumping all your crap.

The side pocket for a water bottle holds a standard bottle, but it falls out if the backpack is laid down.  It could use a little elastic on the top.  The clip on the front is a good option for a water bottle too. I live in the Southwest so having water at all times is critical.  The wheel wells block the backpack from being able to hold a standard binder.  I put the smaller books behind the binder, which is opposite of my normal.  Easy adjustment and the pack opens nicely and widely enough to get to everything without difficulty.

There is also a front padded pocket inside the main compartment.  I don't normally drag my laptop around, but it fits in there well.  I think I have a 15" laptop.

A classmate of mine has a similar product from the same manufacturer.  Its the bigger version.  It definitely holds everything, but it is too much sometimes.
