I have had such a positive experience with this developer, that this is the first time I have registered to leave a review in my 4 years of experience with joomla!
Not only does the product work just the way it should, but it comes with all the modules you could need.
Support is absolutely top notch. Questions are always answered promptly and are extremely helpful. Even helping me solve a problem that was being caused by a 3rd party extension.
Don't gamble on any other social extensions, do yourself a favor and go with these guys!
