Delsey Helium SuperLite Trolley Tote

Pros: It is extremely well designed with pockets and sections for a variety of items.
It moves very easily and very lightly, virtually no drag.

Cons: Not a thing.

Pros: quality

Cons: extension bars encroach on interior space a bit

Pros: The back strap is convenient to park this atop the 22" carry-on.

Cons: Bought this to use as a wheeled briefcase. It has several mesh pockets, but no little "sleeve" pockets for pens and pencils.
The bag will not fit in the overhead bin on a CRJ-700.
It's a minor point, but the slide-out (attached) luggage tag has a line for "ADDRESS." I don't expect Chinese workers to know English, but this is a quality control issue.

Pros: Separate space for clothes and laptop. Really good value for money. Easy to roll

Cons: Will not fit under seats in some aircraft.
