Hi

Looking to buy amber teething necklace for my little man. Touch wood haven't had any issues with teething yet (6 are down) but with molars etc still to come want to be prepared. Just wondering does it make that much of a difference as to where you get your amber teething necklace? I've seen on line that you can get them ranging from $22 to $40 (Amber.bebe). I don't want to save the $18 and get something that doesn't work but also don't want to spend $40 if I can get the same thing for $22?

Thanks
