Why can't the three-way handle make high-definition vibration?

The reason why the three-way handle can't make high-definition vibration is that there is no patent. Because the first and second parties are Nintendo brand and the third party is Beitong Zeus brand, although the third party has excellent feel and grip and many functions, far exceeding the first and second parties, the nd patents of the first and second parties are still unavailable to the third party. If the third party adds the original functions on the basis of all the functions of the first party and the second party, it will directly replace the first party and the second party, and the first party and the second party do not exist.
