Easy to use with no learning curve required!
It looks how I wanted it to and interacts with my template and all other modules wonderfully. I would love to see the option to show the buttons in all articles of a specific category but this option was also not included in the other plugins I tried. I just emailed the developer and asked about this feature.
Very useful with many options (but not as many as some paid options). Though not a graphically rich backend it is still very clear and easy to work with. Everything it does is done with excellence at the price of free!
