I purchased this luggage set back in January 2019 and did not want to write a review until I had to actually use the product for a true testimonial. This luggage set was used for an international trip from Dallas to Qatar to India. The luggage set traveled on the following surface types: dirt road, mud surface, stone, concrete and asphalt. The wheels performed without any issue and the baggage returned back to Dallas without any damage to its wheels or outer surface. Overall a great product and will purchase again.
