I have used fully automatic electronic triggers and they don't match anywhere near as good as the Response Trigger for the Tippmann A-5.
Marker Setup:
Right now I have Tippmann A-5 with a Response Trigger being the only thing extra on it.
Strengths:
Pretty much automatic
Weaknesses:
You can go through a lot of paint
Review:
The Response Trigger for my Tippmann A-5 has helped me out alot in the wars I have been in with it. I've only been in 2 major wars with it but in my first war during the five rounds I played I managed to get 18 people out. I owe every single kill to the Response Trigger because it pulled through as I dove, shot, ran, and fell, without a single problem.
Conclusion:
I recomend this product for the paintballers who want to provide heavy fire and push the trigger to it's limits.
