Product review (1 stars): Buyer beware!!
This product is misrepresented! Contrary to product description, it has not been endorsed by any leading Rabbi. The endorsements on the product's website were forged. One Rabbi write a long letter permitting the use of the KS in limited circumstances, such as an invalid who is in a life threatening situation, and part of the rabbi's letter was conveniently cut off, making it look like he approves of use of the KS in all situations. Another Rabbi could not get his "approval" off of KS's website until he got his lawyer involved.

Stick with a product that doesn't have to resort to misrepresentation and misquoting in order to sell...
