Took this on a month long trip to Italy  -

This worked well for several weeks of mixed clothing at the change of climate in Oct.
The four caster wheels worked well, needed to use it on two wheels for the cobble-stone streets in Rome and the bridges in Venice.  Convenient strap handles on side and top that are comfortable to grab yet fold flat when not in use further reducing the external protrusions that could affect stowing in A/C compartments.

Very impressed with both the construction and looks.  The extra compartments (external) were very helpful. There is one internal small zippered pocket that also let me stow some small but needed to be accessible items.

I bought this unit as it is at the current limits of acceptable carry-on bags when you also consider that some require everything to be within the dimensional limits. The expandable section allows the expansion of the main compartment by over 1/2 inch - really helps - especially if you are using this instead of a larger suitcase.  It's size forces you to take greater care in what you take - it also makes it easier to haul around town to accommodations and within transportation areas.  I did take one small carry-on to stow some light but bulky items like two sweaters and soft shoes. They were easy to strap on top of the case with my small laptop case.

Totally recommend this carry-on.  Meets carry-on limits yet with expansion lets you take a lot more if you want to check it in.  Gives me a case that I can both carry-on or in it's expanded mode carry more and check it in as luggage.

Good price for the quality you receive.
