The luggage has been on 3 airport trips within a 2-month span.  It has endured multiple connections and dropage.  This luggage is great for the price you pay.  Yes, other luggage is better, but not for under $300.  This luggage is far better than Walmart soft-sided luggage that would cost the same amount of each individual piece combined.  The wheels work great and move in all directions.  The luggage is easily cleaned with a Mr. Clean Magic Eraser.
The smallest piece of luggage flies all airlines in the overhead bin.  I traveled on Southwest and American Airlines with this luggage. The small is the only piece that will work on AA as a carry-on.  The small and medium will work for SW as a carry-on.  The large works for both SW and AA as a checked bag, with a 50-lb restriction.
