CVF Racing water pump?

besides the low price what advantages over a milidon high flow water pump ? I've been using the milidon for over 7 years never had a problem . For that price i might buy one as a spare always good to have spares
From what I’m seeing here and elsewhere is this CVF pump is exactly the same as the PRW pump which are both Chinese copies of the Edelbrock pump. The impeller size and how it fits in the cavity looks to be a better design than some of the other offerings, I’d think it would be a little more efficient moving the coolant. I just bought one regardless!
