ExcellentAs an airline pilot I bought this bag to carry my required work items for when I just have a single day trip or a very quick overnight with just a few toiletries. I've also used it a few times as a carry-on and it does fit under the seat in front just fine, though occasionally on some airlines the aisle seat space is smaller and may be too tight. I give it five stars keeping the price in mind as nothing else compares for less than $100. The caveats are durability and the handles. The Velcro on the handles is not sufficient and wears out too quickly and they are a bit flimsy. The handles themselves seem like they use too light/flimsy of a material compared to higher end options. My bag wore out after about 18 months, but here I am about to order another one. The design, including having the opening encompass part of the "top" of the bag work great for a flight bag and the durability and handle issue is actually not so bad given the low price point compared to other options.Strap to attach to larger bag was a necessity. I spent hours looking at it and in the end neglected tonote the lack of a strap.I took my new Carry-on with me on my first trip over Christmas. First and most important was that I could pack alot of necessities that I need to have with me in case my luggage gets delayed.Second most important was that it would fit easily under the seat. It did.The third criteria was not quite as great. I initially wanted luggage with spinner wheels but opted for this because it was good otherwise. I found that it was smooth riding most times, but when I had to navigate in crowds it got a little squirrely. It bobbled around until I could find a clear, straight path.This will not deter from using it in the future. I would just mark this info as good to knowIt was the perfect size to bring on board planes. It holds enough for all items needed over night incase your luggage doesn’t arrive at you final destination.Rolls pretty well… Handle is adequate… Could be a bit more sturdy… I’ve only used once and will be using on a return trip so we’ll see how it holds up but so far it is very nice and there really is a lot of room inside.This is just what I was looking for after I saw my sister with her rolling under seat bag from another manufacturer. Hers is pretty and sexy and more expensive. I was willing to give up pretty, which after it gets kicked around enough in the airport, just isn't that pretty anymore. I read reviews all over on everything out there and finally decided on this Ciao Rolling Bag.For one thing, it looks just like the ones the flight attendants use for themselves. They must know something. Secondly, it had the features I wanted: lots of outside zippered compartments, zippered compartments on the inside, a sturdy double telescoping handle (the one thing everyone seemed to complain about with the "pretty" ones is that there is a single telescoping handle that wobbled after it was raised.) and a durable fabrication on the outside. This Ciao meets all those requirements.It actually has more compartments on the outside than I could see before I ordered it. There is one in the front for tickets, documents, etc. Then there is one right under it that perfectly fits an iPad or other tablet. There is a outside compartment on each side that will either fit a water bottle, pair of shoes, or whatever. It is deep enough to hold those things, unlike some complaints I read about other bags. What I really appreciate is the very sturdy double handle at the top that uses Velcro to keep it together. This configuration allows me to attach it to my other suitcase so that it can piggy-back on it. That REALLY makes me happy. It is so secure that I do not worry about it falling off and eliminates the need for a luggage bungee cord because I actually put the double handle over the double telescoping handle of my larger bag. Perfection!The inside compartment snaps securely shut so that after you have packed a myriad of wardrobe necessities, they will stay snugly in place. (It does open up so that you can see the entire inside of the bag. The pictures do not really make that clear.) Smart packing and not leaving air spaces all over will allow this to hold, oh so much. YouTube has some videos on how others do this. Fascinating to watch all this stuff come out of such a small space.I have not found anything about this bag I do not really like. So glad I opted for practical over pretty. I did read a complaint about the zipper pulls. What's not to like? I can see them practically in the dark, they are so big. Nope. Love it.The carry on handle does not always fold back smoothly and gets stuck
