I did a three page feature article on them in a archery magazine. A great, innovative product from a Pennsylvania based company.
Because they be be removed and placed on many different areas, the shooter can tune their bow to find the sweet spot for vibration and dampening. Many tournament shooters are saying that they can actually improve their accuracy by tuning their bows with HushPuks.
I use them on my crossbows. Love them!
I support all hunters, regardless of weapon or technique!
