Bests & Worsts Reviews from Amazon

I see that most people love the tumbler as do I. I use it primarily for coffee and find that it keeps it hot for hours. I did have the same complaint as everyone with not being able to remove the sliding mouth cover that clean it. However, with that being said there is a way to remove it. Whether or not the attached video shows this is functioning as designed or not, I'm not sure..... but if many people are willing to throw out a $20 + tumbler because you cannot clean it then what do you have to lose. I have been using two of these mugs for the past several months and continue to use them without fail.
