Looks safe Rated 3 out of 5 stars

The entire download is an XML data sheet, not even a true extension. It adds a search engine to your search engine list, *definitely* not something that can override your homepage or hijack your browser.

As for how good the ringtones are, or how cheap, I can't say. Didn't download any of them.

Not complete enough a package to be safe Rated 1 out of 5 stars

Looks dodgy. I suspect any redirecting homepage, but the whole package here is promising a lot without much accountability if they hijack your system.
