Simply works, no faults.
Not one that I've found
While I'm not familiar with other scramblers, I've been using this one since 2006 and unless I read about a better one for less than free I'm totally sold. At least check it out, but I'd advise downloading. The feature which isn't commonly known is that when you've done a search and don't want to spend time reading the entire article, you can tweak it to locate any word you type in it just appears on the page. Then if that's not the correct usage within the article, you merely have to press Control+G (Windows) to locate the next usage.
