Excellent, exceeded expectations
I was expecting i would find this roll-on a compromise - not as smart as my "business" wheeled cabin bag, not as functional as my osprey and lowe (non-wheeled) carry-ons.
I was wrong, its very smart, well laid out and both the rucsac strap system and the wheels are excellent.
When carrying it on your back its rigid, so I doubt I'd like to carry it miles, but I've done about 800m no problem. I really like how easy it is to get the straps on and off.
Only gripe - the little black feet in the stand broke with tens mins of my first use. I've superglued them in place now and they work perfectly.
All in all its a magic piece of kit that has successfully replaced both my business and "outdoorsy" carry ons.
