Used this product on new years eve 2017 and it was awesome. I bought 3 different boxes not sure of the other names but can describe the color shell. This Echo in the Air (yellow shell) blows lower in the air with a loud bang. There's a (red shell) blows higher in air height with a loud bang. There's a (silver shell) that blows mid in air height with a loud bang. All great products will buy more next year.
