Functional, lightweight, and, unlike Heys, actually within the dimension restrictions for carry-ons where I typically travel. If you do check it, it's super easy to spot when waiting for your luggage after your flight.
The case is slightly springy when pushed so I expect it will be more resilient to cracking than harder cases. The surface texture helps to hide scuffs, but the material isn't as resistant as I would like it to be. The luggage handle material feels cheap but it also seems sturdy enough to get the job done, so I can't complain. The wheels are great so far, no sticking or collecting of gunk on pavements. I don't expect it would be fantastic on cobble or other uneven surfaces as the clearance is low, but that's not really the point of a carry-on spinner, is it? I would've liked to have a waterproof section in the interior as well, but since this is a carry-on size I've got no problems making due with a loose watertight bag.
