I purchased pieces to go on a recent trip and it didn't work for me. I got the new "lightweight" luggage and it's not that light. Also, the totebag that comes with the 22" bag was cheap looking and refused to stay put on the bag and everytime I stopped, it toppled over. It was a major pain and to think I really studied this out before I ordered it!
I have never struggled so much with luggage in my life and wouldn't recommend it. The under the seat piece didn't fit under the seat either....it had to go up in the over head compartment.
