Blankt garantibevis?

Når stangfabrikanter som eksempelvis Scott skriver i deres garantibetingelser:

” Important - The Scott Lifetime Warranty applies only to the original owner and must be registered within 30 days of purchase. Unregistered or resold rods are not covered by this warranty.”

Eller som Hardy/Greys skriver:

“For this ULG to become effective, you must register with us within 21 days of purchase” og “The ULG applies to the original owner only.”

Når andre fabrikater har lignende ordlyd I deres betingelser, er der så overhovedet nogen værdi i de uudfyldte/blanke garantibeviser mm., som der ofte fremhæves i annoncer for brugte stænger?
