At INFODAD, we rank everything we review with plus signs, on a scale from one (+) [disappointing] to four (++++) [definitely worth considering]. We mostly review (+++) or better items. Very rarely, we give an exceptional item a fifth plus. We are independent reviewers and, as parents, want to help families learn which books, music, and computer-related items we and our children love...or hate.
