As is consistent with the complaints filed on the "Rip-off Report" site, these clowns lie through their teeth (sweet young thing "Karen" on the phone assuring that you've been selected based on a previous "survey" she conducted for a new product development) in order to get in the door. They also offer a number of "free gifts" for your time in participating in their focus group - none of which actually materialize.
All they are trying to do is sell you a (very pricey) vacuum cleaner and/or home air purifier or whatever else based on the fact that your family is in peril because the air in your house is putrid. These Bozos make Amway look like Suzie Creamcheese!
