I ordered this trolley bag to substitute my broken backpack because I always carry a lot of books.  I usually love Delsey products for its quality.  This product looks elegant and great.  I like it, however, a few things I'd like to point out for other customers' reference:

1. It has quite a lot of space, but no cushion or any secure protection if you're planing to put a laptop inside.  I'd consider to put extra cushion around my laptop or carry a separate laptop bag instead.

2. The width is 18 inches, but the zipper doesn't close when I put a 11x17 folder in unless I bend it.  It fits up to 12x18 portfolio if you leave the zipper open.

3. It is designed to be a carry-on luggage more than anything else.  However, the top of the bag doesn't look as firm as in the picture.  It's actually more like a rolling briefcase.  The sides don't have separate room for a water bottle or an umbrella.

4. It came with a small lock, however, the lock looks cheap and unreliable.  I'll probably just leave it always unlocked in case the key stops working - which might any time from its rough looking.
