My wife had one of the brand travel mugs and the issue that she is having is leaking. I was glad to give her this insulation mug, which fits perfect for the cup holder. The winter time is approaching and she can always enjoy her coffee hot at any time. She does not know this yet, it is a surprise for her birthday later.
