I’ve been using Joomlaxi components for over 12 months with my Jomsocial sites.
Their products are robust and fill some major gaps however I’d like to make special comment on their incredible support and customer service.
Over the past few months I’ve sent a number of support enquiries and I’ve always received a courteous and detailed response within a few hours.
Lately they helped me with some custom code hacks that any other company would have charged for or ignored. This recent experience just demonstrates their professional attitude towards their customers. I highly recommend these guys.
