Can you wear out a whisker biscuit?

If you can, how do you know when it's time to replace the center assembly>

yes and if you think it is go ahead but one sign is brittle bristles

The bristles become brittle, fuzzy, and in general poor shape. If you are a heavy shooter, I recommend replacing the buscuit every year. They are inexpensive. We sell them for $16. Very simple to do.

Yes you can. I found the best use for mine was cleaning the terminals on my car battery. The acid seems to wear them down quick.

Seriously, I tried the fad, I even understand a local guy near my home invented it. Can't see any reason for using one unless you have problems keeping you arrow on the rest. I gave mine away to someone else on the forum. To each their own.

They usually wear me out.

I did not wear it out, it wore out its welcome and I have it for sale!

Have had mine for three years now and am starting to see a little wear. Why all the hostility toward the buscuit??? I know everyone has their own taste, but I love mine and have shot over 10 deer with mine.

Get a real rest and maybe you'll start hitting those deer!

Yes, and I did so rather quickly. (1 season)

Just curious as to the hatred toward the rest. I gues everyone has there own taste.
