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 Tammy Freeman

I love these mugs. I bought two pieces in different colors. They're fun to play around with if you just sit around doing nothing. It's best to tape the mug to a nearby window or other non-porous vertical surface (we have glass doors in our office) during the conversation and then leave it there. You get really great reactions. When handling hot liquids, you must wait for the air inside the jar to reach equilibrium temperature before sealing it with a lid and then turning it upside down. If you don't spill out of the cup at the wrong time. In fact, not all circles are to blame. It's all about physics. In general, I really like the cup. The first thing a colleague said when he saw mine was what he wanted for his birthday. So definitely a good gift idea for coffee drinkers (I can call them that because they are my people).
