Edelbrock Air Gap Cheap Knockoff

Anyone have any experience with these cheap Edelbrock Air Gap Knockoffs that are on EBAY ?

I know it goes without saying that you get what you pay for but was just wondering if anyone has bolted one on ?

I try to refrain from using Chinesium cheap crapola. It may bolt on and work fine. The problem is these cheap knockoffs undercut the companies that spent a pile of money on R&D to design and test a product. So purchasing the Chinesium leads to the companies we have trusted and relied on to go broke or move into the road apples condominium.
You go to Wally World and buy the "inexpensive", which in actual fact is cheap, socks or shoes. They do not wear well and have to be tossed prematurely as they fall apart.
On top of that, most of the Chinesium priducers are directly affiliated with the CCP and/or PLA which is a hostile foreign government intent on destroying the western freedoms and affluence. Yup, purchasing the real McCoy costs more up front, but these days we need to vote on our futures with our dollars while we still are able to.
