16oz Double Wall Glass Tumbler with Lid, Insulated Glass Travel Mug, Dishwasher Safe & Microwavable Clear Coffee Tumbler To Go, Reusable Cup, Ceramic Travel Mug with Lid

Good cup, it keeps coffee hot for long time. But the issue is it breaks easily. It fell from my hands into the sink and broke apart.

Giving it two stars as it's a decent tumbler. I love the look and feel and the tumbler. The only problem being, it's similar to any other cup you may have. It doesn't keep the liquid warm for periods of time. It's another cup, pretty but not for the purpose purchased. One star deduction for the heating. Absolutely none. One star deduction for the build, it's convinient but seems breakable. One star deduction for the price point. Could buy multiple normal cups at the same price.

Felt almost no heat when held this mug full of hot tea, and the warmth lasted a bit longer then in regular cup, feels amazing but the rubber thingies can get dirty pretty fast

No sé qué tan funcional sea aunque venga chueco. No se si lo puedan apreciar pero el vaso de adentro viene chueco hacia un lado y la leyenda de ecobrew también. Estéticamente ese detalle hace que se vea mal. Espero que en funcionalidades no se vea afectado

Ideal para microondas para no quemarte las manos. Las bandas de silicona se quitan facilmente para poder lavar.

I've been raving about double-walled borosilicate glassware for years -- it does a great job with hot or cold drinks. While it won't keep them hot/cold for quite as long as an insulated steel container, it's still does a very good job, holding the temperature for at least an hour or two. In addition, there's no condensation on the outside. And glass is just plain better than plastic. I was having a hard time finding a double-walled tumbler that had a lid and was protected enough to take in the car, but the ecoBrew is great for at home or on-the-go use. The silicone sleeve and bottom "boot" give just enough protection from slight bumps. Now it's glass, so I wouldn't expect it to survive a hard fall, however. So don't be a klutz! The 16-ounce size works well for lattes made at home (as in the video) or the "grande" size from your local Green Goddess. At first, I was tempted to purchase a similar cup with an all-glass lid from another seller, but I decided the plastic lid on this one was more practical, since it had a better seal to prevent spills. Also, the opening is just big enough for a straw, so it's easier--and safer--to sip while driving. (My car yells at me to "Keep your eyes on the road" if I tip a cup up to drink while driving...) All in all, I'm a big fan of the ecoBrew tumbler and recommend it highly.

It’s like whoever designed this knew exactly what I wanted in a mug. I was looking for a double-walled glass mug with a lid and this is better than I expected. It also needed to fit under my chemex brewer, which this one does perfectly. The rubber on the bottom is such a good design touch too, fit very snuggly, I imagine that’s why they use that strong rubber instead of weaker silicone? The lid’s smell was bad at first but I submerged it in soapy boiling water a few times for a few minutes and it started to dissipate, the dishwasher helped too. I still smell hints of rubber every now and then but I’m sure it’ll go away eventually. If you think the rubbery smell will bother you or if it’ll distract you from the taste of your coffee, you can use it without the lid or just find another option!
