ALTA SERIES Stainless Steel Mug 18 Ounce, Matte Steel/Espresso Black

I love this thing! When you lock the slide lock even under pressure it won’t leak! The open handle is a must have. Able to hang on a car door handle or a wire fence or… Also, Fully (almost) able to disassemble to clean. Only the slide lock doesn’t come off. All of the silicone seals are removable, washable and replaceable. I’m ordering another after 10 months of daily use and abuse on the ranch and job site. Don’t get me wrong, it still keeps my hot coffee hot. I just decided to get another to keep my hot tea hot! Time to retire my leaky Yeti.

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.

Best travel mug I have ever bought. Keeps things hot for 8 to 10 hours!

This keeps my coffee hot for the 3 hours it sometimes takes me to finish it. 4 hours is pushing it, but it's hotter than warm at hour 4. This style handle allows the cup holder in my car and on my motorcycle to hold level, flat and secure. It's thermos quality. Well made. The lid is funky. It allows the cup to seal like a thermos bottle. I suppose some might want to toss it in a brief case, backpack or purse while commuting. IDK. I removed the internal guts to reduce the complexity as I just want a cup with a lid that won't spill much if it gets knocked over for 2 seconds. I wish a simple insulated, open-close lid was available, and this would be my perfect coffee cup. It's 4 stars instead of 5 because I don't need the fancy lid, and it's not available in natural brushed stainless steel. I can maintain brushed SS with 3M® sandlight pads. Time will tell with the grey finish I opted for.

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.

I like this tall Thermos a lot for travel in my car and/or outdoor events. It is well insulated. Its tall shape fits into car cup holders. It has a good handle. And finally, it has a well-fitting lid with spill proof drink spout.

Love this cup. Have used this for over 10 years

I wish I read the 1 Star reviews before ordering! It's a very nice cup and I was excited when ordering it, since I'm looking for a mug to use at drive-thru coffee places and avoid paper cups with chemicals in them. I get the cup and wash it for the first time and took the lid apart. That's when I realized buying this was a mistake. Odd locking / unlocking design where there is no clear line of coffee flowing, it's blocked by this middle locking piece and my drinks would flow over and around the plastic parts. I don't like that at all. I'd like as little plastic contact as possible with a direct flow from the mug, when drinking. I think the lid is very poorly designed, in my opinion. As others have mentioned, it's not the same lid as in the picture, at least the one I ordered in Feb 2025. it's I'll be returning it or throwing in the trash.

Desafortunadamente el producto llego roto, lo voy a regresar...
