Rated 4 out of 5 stars

I haven't tried all the features, but it's worth the download just for the site filtering! Who needs search results (for products) cluttered with webspam like bizrate.com, buy*.com, dealtime.com, insiderpages.com, nextag.com, pricegrabber.com, shoplocal.com, shopping.com, superpages.com, & webclassifieds.us? These "lists of sites" web hits are all about browser ads and click referrals, and reduce the usefulness of the Google search. The filter capability of CustomizeGoogle helps clear out the clutter.
