Review on ☕ Mighty Mug Gray Plastic Travel Mug, Double Wall Tumbler for Cold and Hot Drinks, No-Spill Design, Cup-Holder Friendly, Dishwasher Safe, 12oz Capacity by Dana Black

I originally bought this for my 96 year old father who had trouble tipping over drinks at times. It's amazing: if you lift it *straight up*, it will rise. If you hit him from the side, he'll stay in place. Does not affect the surface it is on (does not scratch). By the way, it works best on *smooth* surfaces, not porous or textured ones. So, fast forward, my fabulous father passed away. I have a medical condition that sometimes makes me clumsy. One of the first things I bought for my table was this mug. I smile at the memory of my father. And of course I don't spill coffee on the keyboard. Hooray. A win-win situation.
