Just so you don't feel like you're talking to an empty room....I picked up a Monos carry on back in December but have yet to actually use it. I wanted a hard sided bag for business travel, unfortunately I haven't had ANY travel .
I've been eyeballing their compression packing cubes as well. When I can finally travel again I will be SO ready! Carry on only here I come...
The bag itself appears very well made and intuitive. The wheels glide smoothly on carpet as well as on hard surfaces. But I have no real world travel experience with the bag.
