Yes, there are a number of more expensive triggers around. But could I tell the difference? I doubt it.
When the certain product-quality is reached, the thing to blame in case of responsiveness acting weird are not the triggers. Are they correctly installed, is the drumhead all good, does your module have the right settings? So far, over the course of more than 18 months of use, I have not a single time found a fault in the triggers themselves.
The price is what it is and you get what you pay for. I see no reason for anyone buying to be dissatisfied with the product.
