Best tumbler ever


I purchased the turquoise tumbler and absolutely love it. It's made of quality plastic, has a durable straw, and easy to close lid. The best feature is the design of the bottom of the tumbler which prevents it from being knocked over. With a small child around, this is a great invention.More > < Less




Perfect for person that has Parkinson's Disease that has a problem with always knocking their drink over.


It really stays upright


I constantly knock over my cup so this is really a great product!


Too tall


I bought this for mom for her nightstands. It's too tall and she knocked it over and it spilled. Very disappointing.

About Mighty Mug

No-Spill Mug

Try tipping this cup over. It won’t budge.

Mighty Mug is a no-spill mug that uses Smartgrip technology to create an airtight seal against flat surfaces, so it can’t be knocked over. It only lifts in one direction: up.

Whether you’re reaching for a drink in the living room, at the office, or outside, you don’t have to worry about kids playing, tails wagging, or people (including you) accidentally bumping into it.

The team of designers behind this liquid life saver adapted its tip-proof mechanism to different drinking vessels.

Coffee drinkers will probably opt for the stainless steel travel mug. This double-walled and vacuum-sealed mug keeps a drink hot for 6 hours or cold for 12. If you’re chilling on the porch on a sunny day, the tumbler is a good choice. It keeps the ice crisp and your hands dry. Finally, the tough, shatter-proof pint glasses come in pairs so you can share the tip-proof experience with a friend.

Whether you use one to protect your keyboard from a spill or just dare a guest to try to tip it, Mighty Mug is as practical as it is impressive.
