my son has very severe biting habits and was constantly chewing anything he could get his hands on, couches, chairs, clothes, dvd cases. i saw this and was dubious about getting at first as it was pricey and i was worried he wouldnt use it. but i need not of worried, it was an instant it, everytime he feels the need to bite he uses his 'chewy'. its very durable and easy to keep clean as u can just wash it with hot soapy water. it did take a while to arrive ( 10 days )but not too bad as it had to come from america, but i feel well worth it as it has helped him no end. i was worried i wouldnt find anything suitable for him, but i would highly reccommend for any one with biting habits that are too strong for normal teething toys. i have encluded a picure of him using it.
