"SuperSync is a breeze to install and set-up… SuperSync does have lots of options, and you’ll need to spend some time in the app to understand how to tap its full potential. But once you do, you’ll be impressed with how much you can accomplish."
"This jack-of-all-trades extends your music collection's reach. If you've ever been frustrated with iTunes' sharing and syncing rules, the free demo is worth a spin."
"SuperSync makes it easy to create a master media library and have a subset on computers and laptops around the house. Any new content that is added on one computer can be instantly uploaded to the master library. SuperSync can help reduce the likelihood that two family members will accidentally buy the same Apple Store download. "

"I’ve been working with SuperSync on my Mac Pro and 17-inch MacBook Pro and it’s super slick and definitely worth further investigation. Indeed, SuperSync supports pretty much all Macs from present-day Snow Leopard systems back to the days of Jaguar, along PCs running Windows 98 through Windows 7. Few apps can boast that level of compatibility."
