This is actually a replacement for me. I owned the same us travler bag and used it many times for the past ten years. It's flown al least 10 times and been lost by the airline twice. It's been on 20 business trips and tons of slumber parties. I only had to replace it because a roommates cat peed on it and I could not get the smell out. Fun Fact : 9 out of 10 checked baggage screeners are always broken. TSA has to sort thru your underwear if your bag is checked. You should pack new undies. The roller bag is completely worth the price. I've never traveled with the small bag because you can bring a bag much larger as your second carry on. Cats don't like luggage.
