I wanted to take a moment to thank you for your fine product. I was concerned about how difficult it would be to install and how long it would take to learn to use your bow anchor sight. It took us about 15 to 20 minutes to install the sight. I was really quite easy with the aid of the video. It took about the same time to make the adjustments to sight in the anchor. Once sighted in, the anchor is truly amazing. I am 49 years old and have difficulty seeing through a peep sight. I have also battled target panic because of the difficulty that I have with seeing through a peep. I immediately removed my peep site before ever shooting my bow. I will never ever ever use a peep again. My groups are tightening every time I shoot the sight. It is not unusual to have 3 of my 5 arrows touching each other. Wow, I am very pleased. It is very easy to correct form errors with your sight. This is one of the best products I have ever purchased.
