Mighty Mug | The Untippable Mug | Grips When Hit, Lifts for Sips | Insulated Stainless Steel Tumbler | Cupholder Friendly | Gifts for Women Men All | Leakproof | 6 Hour Hot / 24 Cold | 16oz | RoseGold

I bought this for a Christmas gift for my husband. The one that I bought him 20 years ago is still in good shape, but the lid got lost. He was thrilled! These mugs are top of the line! Coffee stays hot for up to 6 hours. It has never tipped over once in 20 years of construction sites, toddlers, 1000s of miles of traveling, and camping. The design is beautiful and somehow it fits any size of hand! You will never regret purchasing a Mighty Mug!

We love these! The keep our beverage at the right temp for a long period of time. But the big deal is these dont tip over when on a flat surface.

My better half does light therapy in the morning with her coffee. However, one of our cats joins her and, as cats will, knocks her coffee mug over. This is the solution! No more spilled coffee or the commotion that comes with it to start the day - happy wife, happy life!

I have had this cup for just under a month. The cup works well and keeps drinks hot for long periods of time. I have found 2 issues, the first is the bottom of the cap unscrew for cleaning. After the first cleaning, the piece that unscrews from the bottom will unscrew itself and drop into your beverage. The second is that if you have hot liquids in the cup, it pressurized and makes the valve inoperable.

We guys like functionality and purpose. I saw this on Good Mythical Morning (a morning show) and they really enjoyed it. I got it for all of the guys in my life, and everyone thought it was cool and fun. But most importantly, it works and is useful. It insulates well and is easy to use. The pricing is standard, and I find it to be worth it. It's easy to hold and comfortable in the hand. It fits cup holders perfectly and doesn't fall over unless you give it a really good whack. I wasn't sure if I would like the button on top, used to "open" it, but I do. Do not fill past the fill line or the pressure inside the container will make it very difficult to press the button down.

The Mighty Mug is a decent tumbler with good insulation, it keeps drinks hot for several hours and cold for even longer. The leakproof design is a plus, and it's cupholder-friendly, which makes it convenient for travel. Plus I really like the teal color. However, while the "untippable" feature is clever, it doesn't always hold up in every situation. It does grip well on smooth surfaces, but if bumped hard enough, it can still tip. The untippable part was the only reason why I purchased it because I have a medical condition which makes it hard for me to grip something like this. Without that feature........to me, it's just another overpriced "trendy" mug. Actually, the 16 ounce is too small for me since I drink a lot of water throughout the day. Especially once you add ice in it it's just not enough liquid. Perhaps if they made it larger like a 32 ounce or taller I would've kept it despite not being perfect with the untippable part. Overall, it's a solid mug with good functionality, but it may not be quite as revolutionary as advertised.

It is as advertised. Favorite drinking container.

This stainless steel tumbler is a godsend! If you use a rollator walker to get around, YOU NEED THIS! In the last few months, my beloved Contigo tumbler had started tipping over given the slightest provocation whenever I transported it on my walker tray placed on the seat. I finally decided to get this mug to try solve my problem. When I opened it last night, I was leery that the tumbler would performed as advertised. This morning, I used it for the first time and was delighted when the tumbler did, indeed, stay upright on my tray, no tipping over, no jumping off the tray onto the floor. I loosened the bottom lid cover slightly after reading reviews of "trickling streams of coffee" and there's now an ample, although not gushing, beverage flow. The drink button works fine but appearances were iinitially deceiving. I thought it wasn't staying open when, in fact, it was. The interior walls really held onto the cold radiated by the ice cubes in my ice coffee. The tumbler walls were still noticeably cold when I went to wash out my tumbler. Once Fall hits, I'll test it with hot coffee. I can't speak to long-term durability yet, only time will tell. So far, I'm very pleased with the Mighty Mug. Thank you for solving an out of the ordinary, super annoying, and sometimes, quite messy problem. It intrigues me that the suction action works so well from side to side but absolutely disappears when lifting straight up and that you truly don't have to push down at all to activate the gripping action, just set it down normally. All I know is, it works and the tumbler has erased a huge aggravation from my daily life.
