They claim it's less toxic than Deet and I think it works better as well. I know it doesn't melt rubber or remove nail polish like Deet will. I've been using it in JA for two years now and no bites. They sell a lotion, spray as well a treatment for clothing. I get mine direct from the Sawyer online store as Amazon always seems to be sold out. Here is the link:
