This bag is a great idea in terms of ease of storage when not in use and it has a generous interior. However, in practical terms, it did not serve us well for air and rail travel. It fell over so many times. Even after we re-packed it to ensure heavier items (shoes) were at the bottom, it was difficult to keep the bag upright. Also, when fully packed (40 lbs according to the airline's scale), it had to be LIFTED in order to pull it. Otherwise, the weight on the wheels was too much. My husband tried tilting the bag to pull it on 2 wheels, but the bottom started to tear. I regret this purchase and cannot recommend this item. Lastly, I posted a 1-star review on the Biaggi website but it is not visible. Only 5 star reviews are visible for this bag. That seems shady to me. I emailed Biaggi's customer service 3 weeks ago about my missing review, and I have not received a response.
