I guess it depends on how you use it. my xmpb4's have been used at 600-800psi regularly. only been lubed twice in 2 years. I'll need to service one of them and replace the valve (core) as it doesn't reset properly and is a bit twitchy. basically fired itself under fully auto with a stock WE PDW. however the other xmpb4 or kings had no issue with full auto fire.
