The Spash Infuser is very versatile. Some infusers limit their usage to one specific container. Not so with the Splash Infuser. It can be used with a large assortment of drink containers. (Sports bottles, cups, glasses, thermos bottles, pitchers, etc.) I use mine primarily for lemon water. I love that I can just pop the lemon slices in it, seeds and all. I enjoy the lemon taste and the lemon's seeds are trapped inside the infuser! The product is dishwasher safe so there's no messy cleanup after using it. I ordered extras for family members!
