Absolutely the worst mug imaginable. I could list all the different ways it stinks (like the colors aren’t the same as the picture, etc). But all you need to know is the lip of this mug flares out so dramatically that there is no way you can avoid your coffee running out the sides of your mouth and down your neck. Seriously! There is no way to drink a cup of coffee and tea without spilling it and making a huge mess. Don’t think you will be the one who can use this mug successfully. No one in my family has been able to. I’m very sad I own two of these. I don’t feel like I can return them since I had to use them in order to find out that they are just expensive dribble cups. I suppose I could get them out every April 1 and play a trick on someone yet to experience the unmitigated mess.
