At dx we were given the Bayer Contour meter and BD Ultra Fine lancets to use. We now use the Ping but still use the Contour lancing device and the BD lancets (they are thinner than other brands). The button is sticking on the lancing device and they will not send me a new one until I go buy a box of their lancets. They think that will solve the problem! Its the button sticking not the lancets. They seem to always give me the gears when I phone. Even when I was using their meter too.
