The OSS version is limited in what you can use it for even if you can find it. The paid version is very expensive. Thus, I would never use it for anything where my ethical concerns come into play. However, once you have it running it does appear to work. I've seen production setups that ingest a fair amount of data per day and they don't need a lot of maintenance, which is always nice.
