I bought this suit case to be able to take the maximum amount of stuff through airline checked luggage. When I filled the suit case up with clothes, toiletries, shoes, slippers, and a ukulele, it weighed exactly 50 pounds and still had a little space left. At check-in they measured it with a tape measure and found that it was at the maximum circumference for acceptance. They warned that if it expanded anymore, in the least, it would not be acceptable for checked luggage. The wheels worked great for pulling it around the airports and hotels. The case materials and zipper appeared to be strong and durable, and withstood the air travel, while fully loaded. So, if you are looking for a durable suit case to take the maximum in checked luggage, this is the one.
