Best cup i have ever had. Keeps my coffee hot for hours. A great but.

I don’t normally write reviews but this mug exceeded my expectations by far! It sticks to any flat surface (see photo) and we tested it during a 7 day catamaran sail in high winds. I also liked that you can completely seal it which makes it easy to use as a shaker for drinks. Our captain loved it and since he has a hard time getting mail we left ours on the boat. Yes I’m buying another one!

Bought this for my clumsy wife, who has a habit of accidentally knocking things over. When she carelessly knocked a glass of water over, ruining our wedding book, I'd finally had enough!So I went on Amazon, typed in "Glass Can't Knock Over" and the MIGHTY MUG popped onto my screen!After reading the reviews and watching some videos, I decided it was worth the gamble to save my sanity and ordered one as an anniversary gift. And lo and behold... IT WORKS!!! This Mighty Mug actually IS hard to tip over!Now, I suppose you can tip any mug over if you really want to, but this Mighty Mug is great at resisting and holding up to casual brushes, hits and outright SLAPS that would easily knock over other containers! The suction cup at the bottom holds the mug firmly in place, when hit from the side, but seamlessly releases when you pull the Mighty Mug straight up.It's been a couple of months and we haven't had a spill since! The Mighty Mug did exactly the job it promised to!

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.

My son got me one of these for Christmas one year and I use it frequently on longer road trips. My sister saw mine and thought it was terrific so she got one for Christmas. Holds almost 16 ounces and is almost as insulated as my jumbo Yeti and fits into my cup holders in the car much easier.

I saw this on Amazon in February 2024 and thought, "How cool is this!" I course I bought it and it lived up to the reputation of untippable. And it is leak proof, when the top is closed. However, I found that when opened, the "stopper" didn't go down that far, so it handled liquids pretty well, but my fruit smoothies? Not so much. But regular liquids it handles well, and certainly keeps drinks cold with the double-wall construction.So, I was pretty happy with it, until yesterday, when the bottom of the mug suddenly stopped suctioning. Without the suction cup capabilities, the mug is no long untippable. So, it still keeps drinks cold, and has a leak proof top, but I'm thinking that I spent over $30 on something because it was untippable ... and that lasted only two months.With this in mind, I would never give this as a gift. If buying for yourself, beware that it's likely going to lose the "suction" very quickly.

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.

I got this as a gift for my brother, who has a habit of knocking over his cups, actually it may be a family trait..lol..but it has been amazing! He loves it, has not had any spills and he says it's the best cup ever, and I agree!!
