May Flash FightStick Vibration Strap for F500

Does this work for the Switch yet?

I noticed dbz fighters z (ps4) and street fighter 5 do not have vibration during gameplay. what games do people use this for?

If i get a splitter for jack that the wrist strap plugs into, could i use two of them for both my hands?
