I handled about a dozen of them in January at SHOT.
They are packaged so you can try the trigger. I thought that as a drop in part they were a great value for the quality and change in pull. They gave me one, I just have not gotten around to finishing a build from an 80% receiver.
Of course, a professional trigger job can be both better and lighter. We know any big company is going to CTA and not make them as light as possible.
