Overall I am very pleased with this luggage. I've flown with it twice and so far (knock on wood!) it's held up well. I've also traveled by car on extensive road trips twice and again (knock on wood) it's doing well.It rolls smoothly and the zipper is holding up (gosh...I hope I am not jinxing myself!). :)My biggest disappointment came when I first received the set and began deciding which of the three bags I was going to bring with me to Costa Rica (I could only bring two and didn't want to bring bigger bags than I needed). It was then that I discovered that, given my height (5'8" tall) I don't see myself using the smallest bag (the carry-on) likely EVER.Why?The handle only reaches 27 1/2" high when fully extended whereas my old carry-on bag extends 40" high. The result is that when I attempted to walk with the new carry-on bag behind me it kept hitting the backs of my heels. So it obviously didn't make the journey with me (my old, ratty, carry-on did!).** UPDATE: Much to my embarrassment, about three months after writing this review I discovered that the handle DOES extend higher, as high as my old one. But it gets stuck really badly and jams and that is why I thought it only went up 27 1/2". And, once I do get it up, getting it back down is a challenge. So, update reads: Handle is long enough but jams easily, especially when trying to fully extend it and put it back down.Now as far as the way you pack these suitcases is concerned: I both like and dislike this. Let me explain: I like it because I can get really organized when packing and it holds a lot quite well. By putting it in a zippered part in the lid as well as the bottom part you can do this.But therein lies the downside as well. Unless you're in a hotel room with A LOT of space where you can lay the bag out flat you quickly get disorganized because you are constantly having to shut the bag and everything in the lid gets messed up. If you're traveling alone and have a spare bed in your hotel room you're in luck! But, since I travel with my hubby and he has a suitcase and his gear (he's a pro photographer) we never seem to have enough room. Opened up like all the way (unfolded) the suitcase does not fit on a traditional suitcase rack that many hotels have for your to use, nor does it fit on most other sorts of spaces provided. That leaves the floor and I can't tell you how many times I've stubbed my toe trying to get around it.My husband had a bag with a similar design and he returned his. I won't because, like I said, I both like and dislike this organizational style and the bag's hard sides and VERY good wheels make up for it.All in all, I would say this is the best bag I've had in years. Now, let's just hope that zipper continues to hold up (and, I have to be honest - I've pushed my luck and had to sit on the suitcase to get it to shut!!).
