Review on Stainless Insulated Tumbler by Umite Chef by Vedprakash Trilltight

I drink a few cups of coffee a day at work and was looking for something to cut down on paper and plastic products. I first tried plastic travel mugs but they left an aftertaste that I didn't like.

"Your coffee. After shaking, it is better to press this cover. All in all, the perfect solution to avoid wasting multiple paper coffee cups a day. Update - I liked the mug so much that I bought 2 more 20oz versions when we went coffee shopping. .
