Bests & Worsts Reviews from Amazon

This is a good, safe teether when it is placed in the refrigerator and washed with soap and water per the manufacturer. The bad reviews and photos of melted key rings with slime oozing out of them are posted by people who say—right in their reviews—that they have misused the product by either (a) freezing it or (b) heating it through boiling or a bottle sanitizer. The package instructions clearly state that neither of those are acceptable. And for goodness sake don’t use chlorox or any other household cleaner on it as some reviewers suggest.
