Milty CD lens cleaning disc?

Anyone used this devise? Positive, negative or so-so?

I just ordered one last week myself. I hope it works.

I received the Milty yesterday. I ran it through its paces without using the supplied liquid. I didn't notice anything one way or the other. I guess that means it didn't do any harm.
Hey Krell_man,
Maybe your lens wasn't dirty!? Who knows? Thanks for the update though.
