They're decent. A bit noisy and they'll start to tear your fletchings after a bit. Your accuracy is probably better with a drop-away style rest.
I was waiting for someone else to mention the noise. Really wary animals will hear you draw an arrow through a WB. This leads to shooting at an alert animal at best. Other than that, I like them and it is not an issue for most hunters, because most animals are not "really" wary.
When it happens though...that WB will be in the garbage.
