they reakon every bander will need at least 1 replacement in there lives, my 1st band lasted me 3.5 years and was removed & replaced during the same op, i was unlucky as the fill tube came away from the band end, they reakon 10 years will be average for a bands lifespan, its just like buying a car or a washing machine, nothing lasts forever and will need re newing at some point.
