Ymiko cartridge - is it any good?

Testing the new Ymiko cartridge against a couple of standard Crosley type ones and a Banpa flip cartridge I have a while The Ymiko is also a flip cartridge and basically is fitted with a double stylus with a plastic arm which sticks out of the side. By pushing down on the arm you can flip it over to the other side which brings the other stylus into use. No need to remove and refit it.
