Personal Item Suitcase MINI 4.0 - 16 Inch

This Personal Item MINI suitcase exceeded my expectations! I bought it to use as a personal item on a trip I took on Breeze Airways. It was able to fit under the seat in front of me while I was in a window seat on my departing flight (with the wheels removed), and there was more than enough room for it in under the seat in front of me when I had an aisle seat on my returning flight. There was so much room that it could have fit under the seat with the wheels on. The 4.0 wheels also glide very smoothly (definitely more smoothly than the wheels on the Personal Item 2.0 that I've had for a while). It's also nice to not have to worry about aligning these wheels just right when putting them back on. So far, this is the only 4.0 suitcase I have purchased, but after my experience with the MINI, I will more than likely buy more!
