First up, the material feels nice. That's very important to me. Nice dust silver color. Good bearings inside. Two hex screws on top where the two parts combine. Tighten them down to adjust the angle of the trigger. One screw on the inside to adjust the forward travel of pull/press.
Problem with it is there is no stop for backward travel. Personally, I don't like how I can squeeze the trigger and not have a stop to prevent it from damaging or even breaking the microswitch. If you're really into a certain way the trigger feels like I am, perhaps try out the Critical triggers. I haven't gotten my hands on one yet but from what I've heard it's got whole lot of adjustments you can make.
Does not come with a spring nor cylindrical metal that goes inside the bearing. Ask DYE if yours is missing.
One star off due to the nonexistence of the backward travel stop.
Another star off for the lack of spring and the metal cylinder.
Decent. Good for the buck
