I have used this bag on 8 flights now, all of which had it stuffed to the max and holding right at 50 lbs. The bag performed like a champ and was easy to roll. The inline skate wheels are rubbery and quiet. I also like that it is different and easy to spot on a baggage claim belt amongst a sea of black luggage. Another positive is the telescoping handle because I am fairly tall (6'2") and it keeps the bag from nipping at my heels or having to be bent over and pull it from the sewn-on handle. The construction seems sturdy, and the hard bottom section with zippered divider adds some versatility.

Now for the negatives that kept it from getting 5 stars: first of all the zippers got a little worn and hard to work around the "corners" of the zippered flap. This is probably because I had it stuffed so full, but it doesnt inspire confidence. They are still working for now but seem like they are not too far from breaking and becoming inoperable. Also the things that look like compression straps are only on one side and will only compress one side of the bag about 4 inches. They are pretty much worthless. And the end of the bag it is meant to be stood on isn't rigid in any way, so the middle of it sags and gets dirty/ torn up if you don't have it packed right. Also it is a petty gripe for such a large bag, but bear in mind the bag itself weighs 11 lbs if you are concerned about weight limits for checked bags.

Overall, I like the bag and as long as it continues to function I will recommend it.
