I have installed number of free extensions on my website but this was my first paid product. At first, I didnt want to spend the money, but after reading all the reviews I decided to bite the bullet. And now I am glad to say, it is money well spent. It is a great product with excellent customer service. Installation was somewhat trivial, experienced time out issue which was resolved by not uploading and installing at the sametime. Rather, I uploaded manually and then installed it from there. There are other ways like changing php configuration file but that didn't work for me. documentation is really good. for the most part, integration with social media such as twitter, sharethis, is pretty trivial. However, facebook integration requires some work. But, their tech support goes above and beyond to fix things for you. I have also added Simple Image Gallery which is a must have if you are planning to include images in your blog. Perhaps, they can improve on that in their next version.
Thank you very much for giving us a chance to serve you!
