i no they are supposed to be junk because its cheap and not high quality on somehting that really needs to be dependable but i was curious whats the usual life on them i seen few people say a month and wastegate got stuck open some say year and a half without any problems what kind of luck do you guys usally get. (i no you should never trust ebay for quality before someone jumps my case on even asking a dumb question so i no before you have to remind me)
