Oh the shrinking carry-on.  Most airlines used to allow 24 inches x 17 inches x 10 inches (61 x 43 x 25 cm).  But over time as they have stopped allowing free checked bags more people are carrying on and those overhead bins get full.  So the airlines are making the carry-ons smaller.

American, United, Delta, Alaska, and most airlines have settled on 22 inches x 14 inches x 9 inches (56 x 36 x 23 cm).

Southwest is still holding strong at 24 x 16 x 10 inches.  But they also give you free checked bags so people aren't fighting like rabid animals for overhead bin space..

I'm included a couple photos comparing the current standard size to the older standard size, with the older size being represented by my Samsonite that has logged many miles on many airlines.

As for the Travelpro Maxlite 5 itself it appears to be well built.  It spins like a dream, the handle telescopes up and down nicely.  The grab handles stick out just far enough it is easy to grab in a hurry, I like the grab handles better than on my Samsonite.  Standard features of compression zipper, full length zippered sleeve, and short length zippered sleeve.  The zippers seem sturdy enough, though time will truly tell.  I do wish the compression zipper had a larger expansion, but it is fine how it is.  The weight is quite light.  To get to the light weight there is less padding on the botton (handle size) of the bag than in some other carry ons.  So don't put your laptop on the bottom when packing without a padded sleeve or a layer of clothing under it.  I think the lower weight is worth the reduced padding.

Overall it seems comparable in quality to my Samsonite while being lighter and fitting the new airline carry on dimensions.
