No setup, no reset. The prop is diabolical. You get it and you think you know what it is but it IS NOT - It has a twist in the prop that makes it perfect. This is PERFECT like so much of what Taiwan Ben offers. This should cost $200. The thinking is so great on a new type of prop. You got to get this one gang. I just bought 2 more after getting the first because I want spares and one on me at all times and one in my kit.Effect on audience is stunning. The method creates a ripping sound that is so real it keeps fooling me in the mirror. I love this one!!!!
