The Samsonite Centric 2 Hardside Expandable Luggage with Spinner Wheels (Black) 2 Piece Set has been on 3 trips now with me, and the only wear that's visible are a few scuffs on the exterior of the hardside suitcases. This 2 piece set comes with a 24 inch suitcase and a 20 inch suitcase. The 24 inch suitcase has been through airport baggage checks/transport, which is where the scuffs came from. Although there are some surface scuffs to the suitcases, my belongings on the inside have been undamaged thus far.Pros:* 20 inch suitcase fits in the 24 inch suitcase for easy storage when not in use.* 20 inch suitcase fit 4 days worth of clothing and shoes. Could fit more when expanded.* 24 inch suitcase fit 7 days worth of clothing and shoes. Could fit more when expanded.* 24 inch has TSA lock* 20 inch has USB-A port on exterior for easy device charging via battery pack (not included).* Both suitcases are durable, and have withstood airport baggage check/transport.* The storage sleeve for the battery pack can accommodate battery packs as large as 6 inches long by 4 inches wide, but it would be a very tight fit depending upon the thickness of the battery pack.Cons:* The retractable handles can be forced out of their locking positions back into a closed position with some force. This isn't a deal breaker for me, but caught me off guard the few times it did it in the airport. I recommend not pushing these suitcases and only pull them to help prevent this issue.Overall, this 2 piece luggage set from Samsonite has been great for me! I was surprised that my size 12 shoes fit horizontally in the 20 inch suitcase. The USB-A charging port is very handy in the airport when you can't get to an electrical outlet. Please note: The rechargeable battery pack in the pictures does not come with this set! Make sure your battery pack has a USB-A output port to connect to the USB-A cord in the suitcase. I highly recommend this set to all types of travelers.
