This product has not yet been released to the public. It is still being tested. It has been a lengthy task and the latest incarnation is showing promise. This is being manufactured using a lamination process and it must be proven that it can be stable over a long period of time. It plays long and fast and no heat is necessary I'm sure that if this goes to market users would be very disappointed if it were to de-laminate and render it useless. So wish me luck and hopefully someday this will be available at an affordable price.
