Kisser Button?
 

Is a kisser button effective? Are they worth the speed loss?
How many of you use them?

Thank You

LOL at speed loss. Just stop that kind of talk right now. Its an aid for accuracy as its an additional anchor point. That trumps 1 or 2 FPS. Corner of the mouth, tip of nose, eye in the peep and bend at the waist and enjoy more consistency and accuracy and the nearly unmeasurable loss in speed wont bother you a bit.

What speed loss? They weigh like 5 grains. Anything that helps you anchor more consistently is a good thing.

I've always used a kisser and peep together, solid anchor point all the time. You wont even notice the speed loss. They weigh virtually nothing.

Ditto to all the answers above. BTW - DIY is correct ANYTHING on the string will reduce speed. But a kisser's reduction is insignificant but the consistency factor is improved.
