I have used the original black eliminator buttons for 20 years and this latest version (brown) is junk by comparison. So far the only button of 5 that has not shot out is the one I use for a kisser button, the others have been destroyed in less than 100 shots each. I pulled the last remaining black button off my old bow and hope it will be get me through the season. The brown buttons are considerably softer and less durable. Regardless of what Neet claims, the original is far superior.
This past year I tried these buttons in a large quantity through out the string. They did help quiet bow noise and I use them instead of a crimped nock.
