This is the 2nd full set and in total have used 7 Ryders. A couple of international trips is what they've been tested on as yet. The bags have withstood them reasonably. They do tend to get scratched, but no major issues. Wheels are smooth. The zippers are strong. Unfortunately Safari does not pack them well during dispatch and the mid-sized gets a lot of scratches by the time it reaches you. Maybe they can also work on the total weight a bit. Packing 32 Kgs in the biggest is sometimes a challenge. Overall a great product at a great value.
