Hello guys, I just want to let you know the member called prismed or something and her/his web site is prismmedical.com is a liar, he claims to be a doctor in Florida and he is not and he would not answer my q. so I just do not want any one to get fooled, the thing is he/she does not has to lie but they did and that is a red flag, and their products are friggingly expensive, so that is just warning from my experience with him/ her
