I have a softball team, after games rather than playing 'bags' AKA 'cornhole' we started playing 'Poleish Horseshoes' AKA 'Beersbee' (YouTube it if you're unfamiliar). It got to the point where regular frisbees were hitting our opponents in the face because the visibility didn't allow for enough reaction time, especially because we always played at night with different lighting situations. So I bought this & WOW! was I surprised with the quality. The disc is so bright you'll never lose it as it's flying at your face, no matter the speed. It's taken a beating, going full speed at brick walls, being kicked around as a soccer ball on pavement by a fellow who'd had more than his share of libations for the night. It's had alcoholic beverages spilled all over it & it's even been nearly completely submerged in puddles of water more than once. It's never even turned off without me intentionally clicking the button. It's gotten so popular amongst friends that I've been requested to bring it over to get-togethers & BBQ's. This is a product you didn't know you needed.
