Very well

Very solid, as for that price it's WORTH IT! Stiffened at the saddle, which eliminates swaying

Very practical, easy to install, highly recommended. The only thing I will modify is that the big bag doesn't have a closure at the end, only Velcro, and it seems unsafe to me. I don't think things will fall out easily, but it could happen. I think the next 13-liter bag already has a zipper and is waterproof; I think it's more convenient.

Very good, it moves little. The seller says it doesn't leak, but from experience it perfectly withstands a 2-hour downpour. Weak point: assembly/disassembly is not the most practical, so it stays on the bike.
