ewiz -- no, he doesn't have any proof. Problem is, no one can prove that Tzfuma even exists, let alone showed a profit.
believe me, there have been guys on this board searching for that proof for a long time, and to the best of my knowledge, aside from a website that got started but was then never finished, and that financial report and a PR that said they won't be selling in the U.S., nobody has been able to find anything.
I personally have spent about 6 hours on it in the past in an effort to find something, and I failed miserably.
Believe me, I would like nothing better than for them to be there and making money, but the evidence (or lack thereof) does not support that they exist as a real company.
All my opinion.
