I'll never forget my first experience with one of these. I saw the ad for one on TV when they first arrived on the scene and the promise of a frisbee-type ring that could literally break Guinness World Records was too good to pass up, so me and my buddies chipped in and sprung for one. We went to the local park in our neighborhood, which had (what we considered to be at the time, anyway) fairly sizable stretches of open ground that would be perfect for our needs. I kid you not when I tell you that we only got to throw it once. It flew for hundreds of feet on that throw, caught some air and actually climbed higher and higher during its flight before it got caught up on a tree branch with no feasible way of getting it down. These things are pretty ridiculous. You literally need a HUGE field to be able to play with these things properly and they can get caught on things (like tree branches) easily due to the ring shape. I'll still give this thing five stars because it does exactly what it says it does and it's a LOT of fun in the proper setting. I'd also suggest being careful with this thing. Not just in regards to losing it but if you play somewhere where there's a decent amount of foot traffic, you can take someone out easily. It happened to me and my friends with the second one we bought, when we used the Great Lawn at Central Park for our play area. One man walking by caught a throw square in the face while another one got a shot to the crotch. If you're not looking for it, chances are you won't see this thing coming being that it's so thin and so fast. I actually still have the second one in my possession and it's a great product but heed my words in regards to its capabilities and its potential safety risks.
