Really sorry to hear that Arielle. I did also see the illustrations and recall that, but hadn't realised how important to the process, the 'buffing' (sic) is.
As for the feedback, I first heard of these things well over a year ago now. I've done searching for some reliable feedback but found none. The cost here was about 250 bucks, which is not cheap and for something that will end up in the 'drawer', hardly worth it.
