We use Factget to pull the full file wrapper for a patent from a single application number. That covers the prosecution history, the family members, and the prior art cited against the application, so we don't go office by office anymore. Review collected by and hosted on G2.com.
The only thing I've noticed is that when the source websites are down or slow, runs take a bit longer to finish. It does affect turnaround now and then. Translations and extractions have been accurate for us. Review collected by and hosted on G2.com.
