Having run numerous different trigger bars, flat shoes, hand fit connectors and even short pined ejector housings and can say design and craftsmanship go a long way on improving the factory Glock trigger. With a factory trigger bar, vertical extension and cruciform there's a lot of hand polish and finesse needed to get a superior end product.
Based on the website pictures I would suspect the pre/over travel and break should be better based on design. Curious why they kept a stock style vertical extension shape.
At that market price i'd be tempted to give one a try.
