I got this bag because of the size - having a 21" tall bag really makes a difference compared to the 20" tall bags. I found it really easy to fit all of my gear in the bag, and I really liked all of the handles at the top which make it really easy to lift into my car.
The only drawback was that the plastic ribs at the bottom of the bag broke after about 1 year of use, and then the bag started to sag when I pulled it. Perhaps I abused the bag too much, but I would have thought that it would have lasted a bit longer.
That aside, I did like the bag very much.
