It's a nice cup, keeps coffee extremely warm for hours. Not a super big fan of the top but I was given some better instructions on how to use it and it's better. Its tip over proof as long as your on the right kind of surface, It would be cool if it some how shuts the drinking port when it does fall over.

Love the beer mugs! Hard to tip over, sturdy, and keep drinks good. We personalize them with laser engraving and give them away as going away gifts. Supet happy with Mighty Mugs!

Love it

The mighty mug has been a tremendous help for my husband who struggles with essential tremors. No more falls and spills. Thank you!

Love the cup more than I thought I would. I like the sip anywhere. Push button to open or lock close. Great overall mug for car, home and work.
