D2FC-F-7N: life of 5 million times, feel in the regulation of distance;
D2FC-F-7N 10M: life of 10 million times, feel slightly less than a little bit;
D2FC-F-7N 20M: life of 20 million times, feel slightly soft brittle, silver alloy contacts, shrapnel slightly thicker.
The new D2FC-F-7N 10M OF: D2FC-F-7N (10m) enhanced version, compared to ordinary 7N (10M) real life is higher, and the rebound is even more uniform, is the domestic series 0.74N, the hardest Crisp a, you can use the "rebound simply force off" to describe this section of micro-movement, like the domestic series of hard-bustling players the gospel!
New D2FC-F-7N 20M OF: more uniform strength, the conservative life of 20 million (20M and 10M (OF) is a comprehensive model);
The new D2FC-F-K (50M) (blue dot): similar to the early MS, have the same flexibility, the intensity is more uniform, relative to the 20M OF strength slightly soft and brittle! Life of up to 50 million times (currently the highest life products).
