They look and feel great. They breathed new life into old controllers. They fit snugly into the analog sticks on my Logitech controller. They also fit well on the GameCube controller which still has the rubber pad on it. It's a lot bigger than the raw GameCube controller stalk. I tried to glue it with super glue, but the super glue didn't stick to the silicone the pads are made of. The hot glue worked really well to hold the gasket in place. I would buy it again if needed, but 16 seems like a lifetime supply to me.
