Contigo AUTOSEAL Stainless Steel Vacuum Insulated Tumbler, 16 Ounces, Green

I imagine most people need to know two things about this mug.

1) It really is a terrific insulator. Your coffee will be hot all morning, and probably into the afternoon with this mug. I have found coffee hot 5 hours after I poured it. Hot.

2) It doesn't leak. Yeah, that's what they promise, but the surprise is that the clever and more importantly well constructed lid does not leak. You could store it upside down in your important files cabinet if you needed to. It's a great mug.

Also, I think it looks cool. It fits my cupholder in my truck. It's easy to clean. Those are all nice too.

HTH

My husband called my old car "the cheesemobile," because I often spilled my white chocolate whole-milk lattes between the seats while driving and couldn't clean up the mess before it soured and stank. Hot summers in that car were not fun.

My new car is the same color as this beautiful insulated mug, and the car smells fine because the mug works so well. Screw on the lid and your drink is secure - hot or cold. Simply press the button and drink. When you release the button and put the mug down, the drinking port closes tightly. Knock the mug over and the most that will spill (assuming the lid is screwed on securely) is the one drop that might be left in the drinking port. Keep the button pressed until you put the mug back in the cupholder and even that drop probably won't be there. No levers to forget to close. No lids you need to align, or snap on and wonder if the snap worked.

Because the mug is designed with two-layer construction with an air gap, hot things...Read more

These mugs were the answer to our prayers. reusable coffee cup, lid that worked well, stainless body, kept coffee really hot for a long time.
And then I washed the lids. And reused them, washed, reused--and within a week, my coffee developed an off-smell. The lid smelled like a locker room, and the smell would not go away. I could hear liquid in the lid, and it would not dry out.
The concept is great, and I want these mugs to work, because they're the best I've tried, but I won't buy them again. The lids are just impossible to clean thoroughly, and if you're drinking coffee daily, there's just no way to wash the tops properly. Gross.
