You should be able to fit stuff for a month / two weeks in and full weight at around 22-24kg It Should (like overfull :) When I started the trip I was at 16kg, but you can fit a lot, Even When it Seems it will not go in anymore :)), DEPENDING ON what you have in of course. But weight on general Should not be a problem. You can put a lot of stuff in it and it basicaly has 2 compartments sort of- very useful for a suit if there is a need for keeping something seperate. The clothes did not get much wrinkled Even When super full and with lots stuff Other than clothes in it.
The quality is of course great like Samsonite is known for. The spinner is very easy to maneuver. It gives a great protection and it was really nice to travel around with it, survived the trip without problems and still looks like new. Used it for some other car trips and so and it is great. I also like the look a lot, looks even better to me than Those new series of Samsonite.
Specially for the price I got it for (130-140) It is a Best Buy (imo even for 160-170 (different colors, since a lot of people have black suitcases) is a super deal) and I'm, sure you will be happy with the purchase!
I honestly do not have anything bad to say about it.
