Perfect for what I needed (custom gamepad). I especially liked the slight dome shape on the top surface (hard to tell from the pics). The caps also have a diameter that’s less wide than the button itself, which was a plus for me. Also, they had a relatively low profile compared to other button caps, which fit my project specs. Solid click when pressed.
