Thanks for your input :) That was pretty much the same that I found also. I knew it would be a longshot, but was hoping that someone had used one personally.
Take care, Nicoal
Took a minute to do a little looking around the Internet. Various places you can purchase this. I searched for reviews and did find some. Of course, one can only assume these are legitimate reviews. Here is a link to Amazon with customer reviews.

Sorry, have never used it but have seen it advertised. I'd be curious too to know if it worked or helped.
