Mighty Mug Mini 12 oz Stainless Steel Tumbler, The Travel Mug That WonÕt Fall, with Double Wall Vacuum Insulation To Keep Your Drink Hot or Cold, 12 oz, Silver

The price is a little high, but everything else is terrific. The cup holds firmly and does not leak.

At first I was just looked for a SS mug and didn't realize the special base to prevent spills. It is a combo of rubber ring on top of plastic and gaps. It works quite well to prevent spills, you can bump it with your hand in any direction and it slightly wiggles but stays firm.My wife was trying to pick it up to move it and thought something was on the counter, like food or juice, and it was stuck. I showed her to lift it straight up, rather than at an angle.I don't think it insulates as well as some other SS tumblers, but it is still pretty good and the bump resistance can be handy. Cool idea, and it works.

[UPDATE]The mug has been peeling around the lip - that shouldn't be happening, right? Going back to my vacuum flask. I can knock it over, but at least it's not peeling.

Mighty Mug Mini SS, SilverI was disappointed that there was a flaw in the original cup I received but I am very impressed with the excellent response of the Mighty Mug team - they replaced the cup in a timely fashion and it is fantastic..... it is perfect for using at the computer or anywhere for that matter. Good quality materials, maintains temp, and it doesn't topple. What more can you want. Because of the service, I ordered three more cups before I received the replacement.

Will not fit under my Keurig K10 mini brewing system purchased at Bed Bath and Beyond, although the specs claim it will . Same SS junk as I've purchased in Dollar Stores previously.It does not keep liquids as hot or as cold as claimed.Be careful when you set it down on Formica or other or other hard level surfaces especially if it is wet as it makes a very tight seal and hard to lift the mug and its contends without spilling...so I guess that all the excitement about not knocking it over is the truth.Seal on the top...lift to drink...works very hard..Cost $6.00 plus for shipping

I hadn't heard of this product until I saw it on Amazon. It really works! I have little kids who constantly knock over my coffee. I haven't had a single spill since I switched to the might mug.I would have given it 5 stars, but sow times the lid leaks a bit. It doesn't always seal on my first try twisting it on. I've never had that problem with other mugs. And it doesn't keep my coffee as hot as my Starbucks mugs. But as far as no more cups of coffee being dumped in my lap by my kids, it's awesome!

This mug is absolutely fantastic! I bought for my son as a birthday gift and he loved it ! It really work and never spills.Thanks a lot ! I recommend it !

This is my 2nd "Mighty Mug" - I wore out the first one over 5 years.Works perfectly - as before - and holds my coffee hot for as long as I need it.Two thumbs up!!
