I bought this toy for my son when he was two.  I cannot stress how much he LOVES these dolphins.  He has played with them every bath time for the past 5 and a half years.  The dolphins have taken quite a beating and are still going strong.  Not only have they been a constant bath time toy, but they have been thrown around the backyard, driven around in dump trucks, buried in the sand box, still fine.  We have a new baby and I will definitely buy him his own set.
