Anyone try the Edelbrock VRS-4250 Carb yet?

It is a knock off of a Holley 4100 series. They were common in marine applications.

There are many excellent Holley knock offs . Why do so many people disparage this one ?
Has there been issues with them ? I really like the features they added . If I needed a new carb the VRS would be my choice .
