The support provided by the Joomlaxi team is exceptional. I had a number of configuration and software issues initially. The configuration issues were resolved quickly and the software issue was resolved after a short while with a minor release of the component.
Well worth the money and there's nothing else like it on the market.
There are some minor things I'd like to see (Jomsocial toolbar ACL being better, but this is down to Jomsocial core coding, and being able to rename the jomsocial menu aliases), other than that it's great.
