How do you stir your coffee? A spoon? Swizzles? Tongue depressors? Stirrers?. All of those so-called stirring solutions are things of the past now. Spoons measure your sugar fine enough, but what a waste to have to wash (or toss) another utensil! Tongue depressors end up making your coffee taste like wood, and those stupid swizzles can't stir anything, are you kidding? What you need is a stirring solution for your hot and tasty beverage that doesn't add to landfill, or impart odd flavors to your drink while actually moving stuff around. Self-Stirring Mug has a finish with a snap-lock lid to keep your drink hot. Don't forget - inside this mug is a spinning plastic disk that frappes your drink into a whirling blended maelstrom of deliciousness. It is operated by two power cells, there is no inside & is to be installed. No more sandy sugar in the last dregs of your drink, and no more spoons!
