I have an HHA and love it! the sight is very easy to move, i usually leave it set at 25 yds and can confidently shoot to 40 with it set like that, the customer service is top notch to, I stripped out screw holes on the sight, (my fault) and called them, i am not even the original owner of the sight and they sent me a new piece no questions asked out the door that day on my bow 2 days later, no charge
