Very, VERY impressed!
I have taken it on numerous trips and it's great! I'm a serious over-packer and typically can NEVER pack in only a carry-on for more than a day or 2. With the capacity allowed in the G-RO, I packed for a 5-day cold weather trip. Sweaters, jeans, sweatshirt and sweatpants, Northface zip-up jacket, numerous scarves and hats and 3 PAIRS OF BOOTS! Plus my laptop, tablet and other miscellaneous items like toiletries. So, so impressed! I packed more clothes than I even ended up wearing.
It was also a breeze to pull through the airport with my tote purse attached to the front, even when inching forward in lines and bringing on escalators (I was worried I would miss the spinner bag functionality here). I will point out the initially I had the tote over the handle and that made the bag feel much heaving as it puts all the extra weight on the handle, but by attaching it to the front of the bag, it let those crazy big wheels do what they were meant to & take on the weight for me. I even tested out the wheels on snow (was extremely skeptical upon seeing this in their promotional video) and it pulled just as effortlessly as on smooth surfaces.
Like G-RO recommends, I packed my boots and heavier items toward the bottom of the bag and had no issues with tipping, even with electronics all in the front pocket and my tote attached on front. Super happy with this bag and highly recommend!
