I like the fact that the snaps in the caps are securely attached to the rim. The outer rim design actually works very well with standard sized hole saws. Once everything is drilled they snap into place very securely, no glue required. The main reason I made this purchase was to build and access my fridge's ice maker/water line. This allowed me to create simple and easy access through the kitchen wall. I don't think you can really be the price of these. There is absolutely nothing wrong with their quality, they are made with a well fitted girth and a solid snap-on center cap. I've bought other brands in the past that somehow couldn't use them. I would recommend them.
