My latest use of these adapters has been just as unreliable as the gold ones were. They seem to work just fine with Mono Price connectors or those connectors on Monoprice equipment (such as their cameras). Try to use these on any standard BNC plug and you will quickly see how unreliable the connection is. The center pin is too thin.
CONS: The center pin is too thin. This item has changed from what it used to be.
