Just installed mine three days ago and love it. Very easy to install and what a difference it makes. It does not even feel like the same bow. I did server the contact point of the string. STS provided some serving. It make sense to serve the contact area. I will see how it holds up. I did have concern initially that it would be in my way since I use a Steady Ready due to an earlier shoulder imjury. So far so good though. My groups are tight at 40 yards and I am very pleased with this product. I will be purchasing two for my other bows. Hope this helps and good luck.
