I've had 2 Clay Delays the past 5 years and don't go to any of my ranges without one, as I am there to shoot not sit around and play cards. I had a glitch in my first one and Bill took care of it and payed freight back at no charge after I had owned it well over a year. I upgraded on my seconded one so I could do report pairs and other options. The other brand wireless I used at another club last summer compared to the Clay Delay was nothing but trash. Mike
