my son and I love this - it do exactly what the product description say . it look pretty good and my 8-month old boy love to mouth and chew on this ... the actual teether bit and whatever bit of cord he manage to grab on to as well . so far it have be a huge help in get we through church , dine out and a number of flight with minimal fussing . we mostly use it with I wear it as a necklace , but it also make a fun ` batting ' toy if you dangle it in front of he or fasten it over he car seat handle -lrb- supervise of course -rrb- . I only give this 3 \* for be a ` fun toy ' and ` eductaional ' because it be not really a toy or design to be fun -lrb- ! -rrb- and I be not sure how educational you could say a teether be - these rating be not at all mean negatively - it be just that what we be be ask to rate be somewhat irrelevant to the product itself . definitely a great buy and I have say on many occasion how very glad I be to have it . not quite a ` must-have ' item but almost !
