Was the phone solicitor "Krane Products"? I have bought some of their
stuff in the past, but have no idea if it realy does much or not. What I
do know is the stuff is expensive, and if you ever buy anything from
them, they will pester you to death from then on-- they will not take
"no" for an answer. You have to actually hang up on them, and I even had
them call back right after I hung up on them. Larry
