Phantombuck,I used the Revolutions for 2 years with great success. I switched to the Snypers last year but wouldn't hesitate to use the Revs. again. They do not have a rubber band but they actually have a black rubber o-ring that hold the bottom of the blade in to the collar. There is a groove in the collar and the bottom of the blades have little extensions that are over the groove and the o-ring slides over the extensions and hold them down in the groove. I never had one fail, and I killed 2 bucks, a doe, a coyote and a few groundhogs. They worked great for me.
