Query: Some are not really brass

Got the Gilmour quick connect at Lowe's, and they are brass plated, so they look like brass in the package. But they are really light, and as soon as you start using them the ball bearing keepers start wearing into the male connector, and you can see that it is actually made of a silver colored metal that is very soft. I don't think they will last long.But when new, they do work well.
