WoW, I didn't expect an innocent post about a product to create such flaming reactions from some members.
I certainly have no interest in the product, I merely wanted to give forum members a heads up on it.
I too was extremely sceptical about it's claims & sticking in on a very expensive ML, however I did some research on the net & spoke to many people who had given it a try & it was ALL positive feedback.

My guess is, if you can afford an X5 i'm sure a cynical member here can afford the bucks to give it a whirl & if you are not happy with it or can't feel the difference (i'm sure you will) stick it on e-bay.

Nothing ventured nothing gained
