16oz Jet Black

This is a great reusable cup - looks exactly as it is in the picture, the glass design means it looks very nice and sleek, and it's simple to put together and easy to clean. It also keeps drinks warm for a good amount of time. I was also SO impressed by the customer service provided by Ecoliving! 7 months after purchasing, I contacted them to ask if it's possible to get replacements for the silicone base and holding sleeve (I'd lost them at work after washing them up). They responded so quickly and arranged to send me replacements free of charge, which arrived in that same week. Very pleased! (The only thing I would warn about with this product is that the lid is pushed on. It's a snug fit so doesn't easily fall off or anything and would stop it from spilling if you knocked it over, but it isn't the same as metal flasks with screw on lids. This means it's unsuitable for putting in your bag if it has a drink in it as it could come off if it was knocked around. This has been fine for me as I haven't needed to do that, but something to be aware of.)

A bit delicate so I'm careful with it but I use it everyday to take my coffee to work and it's great not to have to drink out of plastic!

I really liked this mug, as it’s a completely plastic-free option, which is a rarity. Bought it to use at the office and on commutes. Well-insulated, so can comfortably hold the mug without burning your hands. It keeps the drink hot for a long time, which also means I was having to take the lid off to cool my drinks enough to drink them. I did accidentally drop the lid after about 2 weeks, and it sadly smashed instantly on the floor. I’m still using the cup without the lid as it’s fine for office only and still looks nice.

I’ve just taken delivery of my second cup. I broke the last one a few days ago by accidentally catching the rim with a small pan I was moving from the sink to the stove. I’d just made a cup of coffee which was sitting in front of me and then I caught it at the wrong angle and it shattered, quite spectacularly I might add. Very fine, thin and sharp glass went everywhere. This is to be expected though because the glass is thin and without getting sciencey, the double-walled insulation wouldn’t work. A small price to pay though for how effective it is - just don’t break it! When I received the original, I kept meaning to write a review but I have a bit of history with reusable cups in that they never end up being as good or as practical or as reusable as sellers claim they are. I’m primarily a tea drinker, one of those annoying purist (temperature, colour, flavour etc.) ones and I got hacked off tasting plastic, bamboo and other recycled materials in my drinks and then soap, after I’d given them a wash to try and get rid of the stains. Perhaps with coffee, the flavour is not that obvious, but still, not great. Even stainless steel is awful for travel cups and glass is really the only option so when I saw this glass option I decided to give it a go. I liked it immediately and planned to leave a review at the time but decided to wait a while and see how I got on. That was in September 2019. Since then, I’ve used it non-stop, including bringing it to Italy where it really stepped up to the plate. Try making a hot cup of anything in the middle of winter at 3000m and you’ll know that you will only ever achieve have a tepid, flavourless, pretty disgusting, mug of liquid. I have used this mug all day, every day. I especially love being able to see all the tea behind glass. Not sure what that says about me but I also like tropical aquariums, glass-bottomed boats and lava lamps. Back in the U.K. I didn’t use it so much in the office or at home, but I did tend to leave it in the car and use it when I went to McDonald’s or anywhere else for a takeaway hot drink. Did you know that Starbucks reusable cups don’t fit into standard cup holders in cars? Too tall so they hit the windscreen. That’s where the obsession with supersizing everything gets you... design over function. On the drive from the U.K. over to mainland Europe it was invaluable. With my stainless steel flask, they were a winning combo but it made me realise how much I miss the old-style thermos flasks made of glass. So, some practical feedback: It’s insulation is perfect for keeping drinks hot for ages. The lid isn’t that great, it gets a bit gunky up if you have milk in your drinks and then when you turn it inside out to clean it, it stretches and gets too big for the cup. I ended up discarding it after a few weeks. The grippy bit at the bottom fell off and was lost in the first week or so. It’s a good idea for protection but not practical. The sleeve is good though. It comes off easily for cleaning and grips the glass well. The glass does discolour if you take your drinks without milk but the glass is easy to clean. you could argue that I’d be better off with a double-walled glass traditional mug with a handle but these are not practical. Anything that is made of fine glass and that has sticky-out bits like handles, has a limited lifespan! Also, they don’t hold as much and are more expensive. This EcoBrew version is practical and no-fuss. Unfortunately they aren’t available in Europe which was a shame but I ordered on Amazon (within 5 minutes of breaking mine) on Thursday or Friday last week and the delivery arrived today (Tuesday). For four days, I’ve had tepid tea and coffee. By the time I’ve made the drink and carried it outside, it’s lukewarm so I really did miss having this cup. It’s a lot more robust than I thought it was going to be, given that it’s glass, but if it wasn’t for my clumsiness, I wouldn’t have had to buy a replacement. When I placed my order, I ordered two so I have a backup. I’m not planning to break another one but I’m not getting caught out again! Recommended!!!

Bought as a travel mug for my car, can't use it for such as the lid is poorly designed as all I can do is take one tiny little awkward sip at a time. And my tea tastes like silicon, because the liquid comes in contact with the lid seal. And the tiny little square hole to drink out of, have fun finding where that is. I've also removed the silicone grip as I don't like the smell on my fingers. I won't use this mug at home either as I already have double walled glass mugs, which have handles and no holes in the lids, so my tea will stay hotter than using this ecoBrew mug. I had to use the mug to find out I can't drink out of it, as it is out of the box, otherwise I would have returned it: it's not fit for the purpose I bought it for.

What an exceptional company! Instantly reply to customers. Offer care and support with full integrity Wow blown away by the client service!

I had a previous itteration of this cup years ago and it was great until i lost it. This one however, I managed to use the sum total of once. To be fair it kept the tea hot for a decent length of time, but it is extremely fragile, I knocked it over in the sink basin ( plastic and no water in it) and it shattered. Whether it's because it was the tall glass or I had one from a bad batch, who knows. Can't recommend this one I'm afraid. Edit: I've been in communication with the seller and I have to say their customer service is first class. Item replaced and I'll see how I get on with it. Hopefully in the future I can change the rating further.

Looks fantastic, leak proof and easy to use. Great value for money.

El vaso mantiene la temperatura un poco más que una taza de cerámica, no dura demasiado tiempo caliente el café, pero lo suficiente para tomarlo a gusto. Lo he usado en el microondas sin problemas, al sacarlo, el líquido está caliente y el exterior sólo tibio. La tapa también es de vidrio. Es una excelente opción para uso diario, considerando algunos estudios recientes donde se menciona que el acero inoxidable 18/8 (como el de Stanley y la mayoría de marcas) al usarse con sustancias ácidas, como el café, pueden liberar níquel. El vidrio, por otro lado es inerte. El vaso está un poco inclinado, no está totalmente vertical, de esperarse para un objeto fabricado artesanalmente, no afecta su funcionamiento y le da un toque "rústico".

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

Es un vaso muy útil el problema es que en el mío después de unos 2 meses de uso se le ha hecho una pequeña grieta bajo el protector de la base (venía una especie de burbuja desde el principio) y ahora el doble cristal está lleno de líquido que no se puede vaciar.

Everything perfect

Een mooie beker in diverse kleuren met antislip bekleding. Houdt de drank zeker 2 uur op temperatuur.
