This is a technology that no other Rapid Fire or Modded Controller manufacturer in the market can even compete with. The SPS technology allows the customer to set their "rate of fire" to any shots per second desired or required for different games and/or different weapons. The SPS™ series Rapid Fire Modded Controllers is absolutely, hands down, the last Rapid Fire Modded Controller you will ever need. If the game you are playing can benefit from a Rapid Fire Modded Controller, the SPS™ series will work better than any other Modded Controller in the market! When new games come out or patches are released, you don't have to purchase a new rapid fire Modded Controller - just change your shots per second for that game and you're done. Buy a Gamermodz Modded Controller for life - not for a specific game.
