My daughter adores this rattle. It is the first toy she grabbed and held onto. It's colorful handles attract her and the beads move from one sphere to the next. As soon as it's in her grip, the sphere is in her mouth. She'll gum this toy all day if I let her. I haven't had any problems with it hurting her gums as some of the other reviewers did. However, she does occasionally knock herself in the head with it. The manufacturer isn't at fault for that....it's just babies' developing hand-eye coordination.  It's very light, despite it's appearance and she never gets hurt. She's been interested in it since she was 3 months old and her attention hasn't waned yet. Lamaze comes through with another winner!
