Has anyone got it in their S? Is it worth it? Is there something better out there?

As always I suggest reading up at a countermeasures forum (or at least look at existing threads here on the topic). The ZR4's are very old and nowhere near the top of the pack these days.

If the forum search isn't working for you then use a site-restricted Google search:
