Got them after a bad experience with one of those "long" trigger extenders. Unfortunately, the reality is that NONE of these things should stay in place for long periods of time unless you're playing with very thin trigger fingers. That means you have to glue them on, so keep that in mind. Also, these "extenders" basically work by clamping a piece of plastic in a place where nothing was before. It's physically impossible that this somehow doesn't affect the function of the trigger, and it does. What you play and how you play becomes an important factor here, and the decision to respond to the trigger can only be made on an individual basis. It doesn't bother me too much and I have a different inventory controller if that's the case. However, these extensions are the perfect size, lengthening the trigger 1/2-3/4 inch and flexing outward, which is also a plus. On a standard controller, the triggers are too short, clunky in shape, and the material is somewhat tactile. slippery, the finger often slipped off the trigger. The real solution to all this would be if SONY would use these extensions as a template for future manufacture of their triggers!
