I like how it's user friendly, so much better than other software out there! It does exactly what we need without being complicated or overwhelming for our team of 3 people who are newbies when using this typeof product/software - they love having everything right where their eyes lay upon them from start till finish!! We have been able make many referrals with just one click which makes us feel good about reaching others through social media sites such as LinkedIn & Facebook because now everyone knows someone else uses Referal factory too. Nothing really but if i had something negative then maybe its not enough support via phone calls etc., would be nice though sometimes emails take time before getting back into inboxes after sent due lack off knowledge regarding issues within system itself..
