I only ever owned one jelly toy (obtained before I knew anything about material safety), and at the time I couldn't handle the size of it so I never used it. Good thing, too - it was greasy-feeling, and thus likely leaching phthalates. It also smelled really bad, and was way firmer than I hear most jelly toys are. Dissected it for fun years later, then threw it away.
Nowadays I don't even look at jelly toys. The chemicals in them, short lifespan, and bad smell keep me from wanting to try another.
