It's simple, easy to use, clean interface and great user experience. My biggest challenge was to get the tracking code to work for my specific products. A little confusing when initially setting it up. But once I got it, it worked. It took about 20 minutes to set up. And it has never crashed. Great software! It doesn't do everything you want - but its free so why wouldnt' you just try? Its really cool, i love how they offer help online as needed (and even paypal if necessary). If you're looking at this now, take the time and check them out..they are awesome!!
