This trigger definately helps you fire faster than the stock trigger. For $20, this is a great deal. I shot around 3-5 bps faster than i normally could have. This is a great upgrade if you are looking into shooting faster than you normally can now. Besides it looks sorta ugly, its a great upgrade. There is some side to side slack also.
This is a great upgrade for your spyder. You wont regret getting this for $20
