Very soothing product for baby's gums that start doubling probably seen it many drool. Practice with slim handle, it adapts perfectly to the little baby hand for a better grip. I did not put the ring cool because the ambient temperature is correct but it is an interesting option when my baby will really make her teeth. The small regret is that we do not know in advance the color that we will receive, for my part, I would rather have green because I have a little boy and is the pink happened ... for the use he makes, it's no big deal, but to this account, I would have preferred a more neutral color like orange.
