16oz Cool Gray

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.

The tumbler is beautiful and does all the things it needs to do. I got it because it’s glass and double walled so it won’t sweat. Went to use it this morning and the glass is cracked on the inside! So disappointing! No idea how it even happened. Updating my review to reflect the amazing customer service from this seller. They sent a replacement tumbler and so far, so good. I’m extra careful with it and very hopeful! But, again, the follow up from the seller to make it right and give them another chance was really great. They went above and beyond. A+ customer service.

Lid has small chip on outside rim, causing leak down the side of cup. These cups are nice to drink from, but I should have known better. I've had several over the years and none have ever lasted very long. This one leaked from the beginning. Big waste of money. Since it's such a time consuming hassle to get this kind of thing resolved through Amazon customer support, I was very happy when ecoBrew reached out to me and offered a full refund.

I've been slowly transitioning away from plastics and this glass tumbler is insulated and lightweight. While it's not incredibly effective at keeping your drink insulated, it is passable. The worst offense is the lid which, for the most part, doesn't even feel like it was designed for the tumbler. It's not uncommon to just size your tumbler to an existing lid, but this lid leaves much to be desired. The gasket seems like it work great in a plastic or stainless steel cup, but it doesn't seem to want to create an adequate seal with the glass. This means even though it advertises itself as "leakproof", I'd say it's more effective at just not spilling everything out if you accidentally knock it over. The silicone bottom is good, but the sleeve is nothing to write home about. It does an okay job but it does like to move around sometimes when you least expect it. Overall, I'm not entirely thrilled with this tumblr and will be looking for something else. It's too late for me to return this so I hope my review helps others to make an informed decision. It just doesn't satisfy my needs for the price.

The ecoBrew All Glass Tumbler is a good choice for an all glass insulated tumbler. The glass part is of course fragile, and fine. It's the plastic lid of the 16oz glass that seems if anything even more fragile than the glass tumbler itself. The plastic lid is too thin, and will break even more easily than the glass tumbler itself. The lid of the 16oz tumbler needs to be a tougher and thicker grade of plastic. Or else the 16oz model should have the same all-silicone lid that ecoBrew provides on its 12oz tumblers. The 12oz silicone lid has the added advantage that it cushions and protects the rim of the 12oz tumbler from bumps while in use. The thin hard plastic lid on the 16oz tumbler offers no protection at all when in use. The ecoBrew borosilicate glasses are fragile, and that is the nature of all thin-walled glassware. If they are dropped or struck against any hard surface, they will chip, crack, or shatter. In my experience ecoBrew glasses are no more and no less fragile than any other glass tumblers. They have to be handled with care. I have several ecoBrew glasses, and I find their advantages make them worth the careful handling they need. They are the only glass tumblers I have that are easily cleaned with no coffee or tea stains or residue. They can be heated / reheated in any microwave. They are top rack dishwasher safe, though they are best washed as you would wash any fine glass--by hand. If you need an insulated tumbler that is near bomb-proof and can take a beating, then glass is not the material for you. If you can be careful about handling, the ecoBrew All Glass Tumbler is very good. The lid on the 16oz model--not good. The lid needs to be at least as strong as the tumbler.

The cup is super cute and works well for what I needed! I love my iced coffee in the afternoon but hate it sweating all over my desk, this was a great solution! I'm trying to stick with glass for my drinkware and this is a good solution, the grippy bottom and ring around it are really nice too. It is a little delicate, so be aware to be gentle with it! Their customer service is top notch too!

EXCELLENT product! The glass is very thin, but the tumbler is designed well. I'm always amazed that I can pour such hot water in without it breaking. It hold the heat well, too. I don't use the dishwasher, but I find it easy to clean by hand. I don't use the dishwasher, I purchased a separate silicone tumbler sleeve with handle, reducing my concerns for the tumbler's delicate all glass construction. But it's the glass that I wanted, and ecoBrew delivers! I've had this and used daily for months. Great value for the money.

Nice idea but the glass is so thin that these break too easily. I bought a couple so that I could rotate between the two and not have to worry if one was dirty. But unfortunately any slight bump and it’ll tip over and shatter.

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.

Seit nun bald 2 Monaten besitze ich den Glas to-Go Becher und meine Bewertung fällt gemischt aus, weshalb ich die Rezension in positive und negative Punkte aufgliedern werde: Positiv: Der Glasbecher ist so stabil wie Glas eben sein kann und macht einen relativ wertigen Eindruck. Er hat keine Scharfen Kanten oder Einschlüsse im Glas, ist wie beschrieben doppelwandig. Er wird nicht sonderlich heiß und lässt sich auch dank des Gummirings gut in der Hand halten. Besonders positiv finde ich, dass man ihn in der Spülmaschine säubern kann denn das ist mit vielen Thermobechern nicht möglich. Die Farbe stimmt mit dem Produktbild überein und bei gängigen Kaffeeketten kann man ihn mit einem kleinen Cappuccino oder Latte füllen lassen, da er über passendes Volumen verfügt. Ferner entstehen durch das Glas (vermutlich) keine schädlichen Stoffe oder unangenehme Geschmäcker, es setzt sich nichts ab und der Kaffee / Cappuccino/ Latte/Tee / etc. schmeckt, wie er schmecken soll und nicht nach Pappbecher, Thermoskanne etc. . Hier aber nun das ABER: Negativ: Der Deckel ist leider nicht besonders hochwertig. Er passt zwar auf den Becher und man kann seinen Kaffee im gehen transportieren / trinken ohne dass die weiße Bluse Flecken bekommt, er ist aber sehr wabbelig, wird in der Spülmaschine nicht 100% sauber und hat einen unangenehmen Plastikgeruch der den Kaffeegenuss versaut. Ich habe hier nicht unbedingt den Eindruck, dass der Deckel gesundheitlich unbedenklich ist (wegen des Geruchs), will dem Hersteller hier aber natürlich ohne Laboruntersuchung auch nichts vorwerfen. Auch der Verschlussmechanismus könnte besser gelöst sein da der Deckel der Öffnung nicht "einrastet". Hier habe ich mir für diesen Preis eine elegantere Lösung, zumindest eine geruchlich neutralere, erhofft. Neutral : Neutral ist für mich persönlich, dass der Kaffee nicht brühend heiß bleibt - denn damit habe ich bereits gerechnet, es ist eben ein Glasbecher und keine Thermoskanne. Außerdem kann man bei solch einem to-go Becher natürlich kein Produkt erwarten , welches man in der Tasche umherwerfen kann ohne Kaffee zu verschütten. Ich würde daher ehrlich gesagt von einer Kaufempfehlung absehen. Die Idee des Glasbechers ist super und an sich eine tolle Sache (und natürlich auch schick), der Deckel ist jedoch eine wirklich unelegante Lösung und mit seinem starken Eigengeruch ein echtes Problem. Ich nutze den Becher jetzt nur noch zum Transport und trinke dann ohne Deckel, aber das ist weder Sinn der Sache noch knapp 18€ wert.

I’m giving it five stars because I’m happy with the product, it’s exactly what I was looking for. I like the design, the size, and the glass lid, it’s double-insulated, reasonably priced, keeps things hot or cold for a decent amount of time, and is easy to clean. Also, the downsides are things I was already aware of, it’s glass (so it won’t survive drops, can break for various reasons, and doesn’t retain heat as well as other materials).

This thing is amazing and it solves all of my problems. I drink lots of coffee. The problem with a metal thermos is you cannot microwave it, either to make coffee at work or to reheat my coffee. The problem with plastic travel coffee cups is they go cold too quick to last my commute. This cup solves all of these problems by both keeping it hot for a very long time, and being microwavable. Also the lid is so good. Lots of thermos have some space age lid with lots of small crevices and moving parts that are impossible to clean, especially with a dairy drink. This has a simple glass lid in the style of a takeaway coffee cup that is extremely simple to clean, and the seal is decent enough it will not spill unless you are like sprinting or something.
