I purchased two of these during the funding phase, one for me and one for my father who travels a lot. We waited almost 8 months to get them, after most of my annual travel was done. My father got his finally and I mine and they sat for sometime as neither of us was traveling. Finally i had a chance and I took it on a day trip from Denver to LA where I flew out and back the same day, and i was not impressed with a lot of the features I was promised The handle is very annoying to use, having to push the button to swivel it doesn't function the same as was originally advertised, usually i'm constantly holding the button to get it to swivel and roll behind me comfortably but then my thumb hurts after awhile, and the button itself is tricky to operate sometimes, my wife could never figure it out. and unless you know the magic tap, the handle is almost impossible to put down.  The bag is constantly catching on its side or Tipping i'd lend due to the center of gravity and the pivot point and the short prop on the bottom, the wheels feel cheap and tons of friction on the axle not the way I'd expect a 'luxury' bag to feel. the velcro over the 'charging port' always catches when sliding the bag in and out of the trunk or over head compartments not to mention how unsightly that is on the side. And the 'collapsible' nature of the bag which was the main selling point is a joke compared to what was originally promised, I think it collapses an additional 2 inches? The tabs that lock it in place are cheap and constantly come out when I'm trying to put it together or disassemble it. And as easily as they pop out and how integral they are to the function of the bag, if you loose one, you now have a worthless lump of fabric, can't even function as a paper weight.  I finally had a chance to use it when I traveled for my wedding across country and immediately from there to my honeymoon out of the US. This was very disappointing. After pulling it out of its bag, I pulled the slot open to charge the battery pack.. and the whole unit fell out as soon as i undid the velcro, you can see where it was just GLUED to the inside, and the glue wasn't holding it anymore, so that feature because useless and I ended up just stuffing the battery pack in my backpack next to the other charger I bought at Bestbuy for 20$. Then After traveling across country we were repacking to fly out of country and one of the zippers broke. The zippers themselves feel cheep and flimsy constantly catching as you zip them, i've had better zippers on McDonalds toys.  I have luggage of the same size that I paid a fraction of the price for this that hold up better, have similar features and out perform this. all the neat features you can easily add, battery pack, scale, tracker.. etc. at probably a fraction of the price, non of these are 'integrated' as was originally promised. I won't even get started on the 'laptop tray' which is just a pure joke.. that is neither convenient or functional, the zipper hold it in is a constant fight.. the tray looks like some scrap plastic laying around from the shop floor, and the integrity of it is questionable. stay away from this product.i'm currently trying to get intouch with customer service/support but enough reviews have made me less than hopeful.
