It holds a lot, as other reviews say. You also can use it as a carry on.  We used it on our trip to Europe for 12 days and it held up great during the few times we traveled to different places we stayed at. It was then used by my husband on a business trip and was fine. However, on his 2nd trip, the bigger strap that you can use- one of the loops broke. It was a trip for only a few days, so it's not like he packed a ton of stuff in there. These trips were within a 3 month time span.

Update: I was contacted by the seller after writing my review and I was offered either a refund or another bag mailed. I chose to have another bag mailed. Due to the customer service, I've updated my review to 4 stars and to let others know how the seller responded. We are looking forward to another bag bc it is nice to use instead of a suitcase!
