I have used the A1 Generator since it first appeared in the market. I first used it to successfully to add  a sitemap to my site, but later tested its
capabilities to the limit by mapping every product in amazon.com, some 4 million products at the time.  I currently use it in other devious ways to
enhance my affiliate sales.  Yes - from my experience it remains the best product of its kind - 10 out of 10.
