yes i got one of those phone calls as well... and sure , everyone likes a prize :).. but it was to good to be true.. so i did some online research.. not only on this site.. but on many sites you can read the complaints. i was almost forced into an appointment... feeling that something wasn't right i pushed it into next week so i  had some time for research.
After reading the articles i found i called them back to remove me from their  call list and cancel my appointment.
Surprisingly fast the lady had my info and said she would do so .......
Lets hope it is going to work for real.

Was there a Derek Smith who worked there, Nicolas?

I work as one of the much-maligned demo guys for Health-Tek California.We are all instructed to ALWAYS ask for the lady of the house, and NEVER for the husband.The reason: research all over has shown that the woman spends more time in the house, has a much larger say in household expenditures, and is much more concerned about air quality in the home because of children, time in the kitchen, cleaning duties, etc.It's unfortunate that so many have had unpleasant experiences with "pushy" reps, but in an organization as large as us, this is bound to happen.If you EVER get a bad feeling about a sales rep, a demo person, a surveyor, or anyone else you don't know, you have the ultimate answer: don't let them in.

I went to that Healthtek "presentation" tonight..and later excepted a job....but after looking online about their business I will not be attending their three day "training" course.

ummm we all think that you're the idiotfor working in that company lol
