Query: Disappointed in this Starbucks Product

I decided to purchase this travel mug because of the Starbucks reputation for quality. However, this is one of the cheapest travel mugs I have used. The rubber grip came apart and fell off the mug after the first wash -- I didn't even get to use it. I am returning it.There are better travel coffee mugs for less money out there. Don't waste your time with this one. It costs too much money to fall apart before it can even be used.
