Briggs and Riley lifetime guaranty
We have four B&R cases, two carry-ons and two large cases. They just repaired and returned one of the large ones and it is more than 15 years old. They returned it looking like new, even replaced the wheels, unbelievable service. I am so glad we switched to B&R ages ago. They're not cheap, but they really stand behind their lifetime guarantee, their designs are good for packing and the products are super durable.
I am not the type to rave about anything but this company takes their lifetime guarantee seriously.
