I haven't tried them out for years, but when I did, it wasn't a good experience. They gave me keywords that were broad, not entirely relevant, and some of the ads had misspellings (!) I shut it down immediately.
But that was years ago, and perhaps they're better at it now. Just remember that they may be optimizing for clicks, and you likely want conversions.
