Customer Review | This is a solid, quality travel mug that I’ve repurchased over the years. They’re leak proof, they have a lock so that if we hit the open button it doesn’t just let the contents pour out. The inside of the lid also unclicks so you can clean it really well. There are some tiny areas that are hard to reach but overall it’s pretty easy to clean. Only complaint is that the plastic in the lid begins to smell after a while which is why I replace it here and there over time.”  Rebecca
