I just received my Sprint Ring. Could throw beautiful, predictable flights straight away. My Border Collie loves it. He puts it over his head to fetch it, which, of course, he can't do with a conventional disc. The soft edge does not hurt his mouth. Because its flight is so predictable, it is better than a conventional frisbee even in a small garden - it is less susceptible to gusts and turbulence and hence carefully aimed and gently thrown it does not sail over hedges and fences into neighbour's gardens. Great product.
