All valid points, no I am not looking to taking people for a ride hence am going to be doing a lot of tests to prove or disprove the claims. If I can prove the product great, if not well I have lost a little money. If it does work and I get the data to prove this I will happily pass it on. Obviously if it does work I would be happy to offer samples to Alfa owners to make up their own minds. That way if it works I get my marketing done in the best way, by word of mouth!
