Like me, people who are fans of MV know them for their service, quick shipping and love the fact that Tony likes to tweak his products with the manufacturer. He's started a physical store front since business is doing well and appears to be happy with some tweaks he's been making, so MV will have some new items in the coming months - including the crystal batteries he had been talking about that not sensitive to sound. I can say they are so nice, it might make me get away from manual batteries.
