Excellent basic Thermos thermal cup.
This was the second of these I have had, my first suffered a crash that broke the vacuum seal, making it inefficient for holding temps. The overall quality has improved since my initial purchase several years ago with some minor improvements in the sealing components and desighn. I bought a duplicate replacement because the first had been so trouble free and efficient at keeping things hot or cold for many hours at a time. It is also simple to maintain, dishwasher safe, and easy to drink from and shut off the well designed lid. It seals very snugly, and the fact that the sliding opening/closing mechanism can double as a bit of good leverage for a good seal and easy take off is a bit of a bonus for cleaning, refilling. Like most Thermos products I have bought and used over my lifetime, it is reasonably priced, provides excellent service, and is very handy to use and carry.

Use It Regularly
I like the open handle so I can hang the cup from my pocket. Doesn’t leak. Keeps stuff hot. I hope it’s still in production when I need to buy a replacement.

Description is wrong! Capacity is 16 ounces!
What can you say, it’s a Thermos. Quality of build and materials can’t be beat. Does exactly what it should and stays hot for hours. Only issue is that it does not hold 18 oz, it hold 16 oz to the fill line, which says do not fill above.

Great mug & dishwasher friendly, too.
Easy to open top to drink from & keeps contents from spilling, too.

My favorite coffee mug
Bought this as a replacement because my lid was lost during a recent move and this is my favorite mug! Iâm disabled on crutches and require a lid to carry my coffee. This lid design is great and has served me well for 5 years. Keeps coffee hot for hours and so many clear plastic lids break and no longer seal, this design makes it practically impossible to break or leak. Just donât lose your lid. Highly recommend this specific model as Iâve been using my first one 5 years.

Long Lasting – Seals Great
This cup has held up very well. After many months of daily use it still looks great. The lid always screws on so it ends up oriented the right way. Other cups have more than one set of threads and it can take several tries to end up with the lid pointing the right way. I really appreciate that. The lid flows well, so I have not needed to drill additional vent holes that other cups have needed. After many months of use, the cup has only leaked once when coffee grounds got in the seal area. The slider that opens the valve for drinking makes an excellent lever to help get the lid loose when it’s time for a refill. Anyone with arthritis will appreciate that. There was only one concern. In recent weeks the handle had started getting loose. I like to hang the handle on my waist band to keep my hands free, so that may cause more than average wear and tear. I could not see any way to get access to see how to correct the problem. It felt like a loose screw was the culprit. Problem Solved! I drilled a 1/8″ hole in the handle where shown in the photo and found a screw buried in silicone. It took about 1/4 turn and the handle is tight again. A 1/8″ rubber plug will look fine and be easy to remove if/when that screw needs to be tightened again. The underside of the lid has lock and unlock symbols indicating how to give a 1/4 turn to unlock the seal and pull it off for cleaning. The seal piece removes and reinstalls easily if the slider on top is in the open position. I use a stiff bursh to occasionally remove coffee residue that can collect under there. I just purchased an identical replacement cup today that I will store in the cupboard until this one starts to look old. The 16 oz size works great for me and Thermos has a short/fat version that may work better for you if the tall style seems too “tippy” for you. The photo also shows the stick-on felt pad we put on the bottom of our cups so they don’t clank when we set them on a table. Sticky back felt sheets can be found at craft stores.

Design changed from pictures. Sometimes leak proof but also drink proof.
I got this yesterday and am sending it back immediately. The design of this lid has changed from the photos shown on the Amazon listing and on the manufacturer’s website. The lid is extremely difficult to thread onto the cup. You almost have to be the Six Million Dollar Man to remove or install the lid. I had to slide the cover latch open and use it as a lever to actually screw the lid on or off. The inside of the lid mechanism has a double ended seal gasket that can be taken apart by rotating a locking knob to the unlocked position, but when putting it back together, the gasket will either seal off the fluid so that you can’t even take a drink, or if you stick your finger inside the bottom of the lid and move the gasket so it’s not sealing the hole, you can drink, but then it’s not leak proof when the gasket isn’t in it’s correct position. It will pour out with the sliding latch in the closed position.The item pictures look like a good simple design but this cup doesn’t have what’s shown (compare with my pictures) and is not a good design at all! Shame on Thermos engineering. It’s not worth the $15 I paid for this on sale on Amazon. I had thermos cups in the past that had the best cold/heat retention of any cup I’ve ever had (easily 6 plus hours hot and almost 12 hours cold), but the lids weren’t easy to get clean and got stinky every so often until I did a drastic lid disassembly to do cleaning. I was hoping this new Thermos cup would have more easy cleaning and also have the same hot/cold retention of the previous Thermos cup! But this new one only kept my drink hot for about 3 hours. I sip my hot tea all morning at work but this one didn’t do the job.Instead, I just got two awesome Contigo Autoseal mugs that have a smart and functional design and are easy to clean. I actually bought them at a local store where I could see and touch the cup and open the lid to see how it functions and if it’s easy to take apart. Great so far.
