This trigger is NOT a magical or mysterious device that makes any guns go full automatic. It is difficult to explain in marketing materials unless the majority of the audiences have a bit of an understanding of the mechanics of shooting fast. I am not the expert but I will make an attempt.
What it does it makes people that do not train to shoot fast easier by having a very strong trigger reset. Instead of using the finger to squeeze and release, this "lazy people" trigger allows the shooter to concentrate on just squeezing and almost nothing on releasing.
If you squeeze the trigger and follow through ( and stop ) like what you will do in traditional rifle shooting, the trigger does exactly like any other trigger will do.
If you are already very good at your trigger, this trigger does not do much at all. On the other hand, if you haven't mastered the trigger, this makes thing easier.
I will venture to say that this trigger is a short cut in training It goes back to the debate where many competent enough shooters shoot their glocks by releasing enough to just make the reset versus where the higher level shooters train to fully release the trigger. If you can only shoot your own gun with only your own amount of trigger reset, you are pretty much a one trick pony.
