I originally got this as a prank to attack my kids getting off the bus in the first day of school but has turned out to be much more fun than I originally thought it would be. I am now constantly sneaking up on friends or neighbors shooting them from afar. If you aim right the 30 ft shot is not impossible making it challenging but super fun. To the paper the 2 ply Scott works the best in my opinion but it will shoot just about any toilet paper I have put in it. Some work better than others but all serve the purpose. The Scotts is just thinner and turns into a spit ball easier than the thicker cottenelle to. My wife has even joined in on the fun. I swear I know it sounds like a dumb toy but I was pleasantly surprised at the fun this has started within the family.
