This has become my go-to cup for my morning coffee. The design is leak proof while still able to keep the temperature of the coffee warm for a decent amount of time. It's not going to last all day, but it's still fairly warm at lunchtime. It washes out easily, though, the plastic can be a bit tricky. I'm a big fan of the glass, too. While it's lightweight, the glass is really durable, and has survived a few counter-high drops. The size is perfect for a tall glass of coffee with some additions, but if you want something larger or need more of a pick me up, you'll want to get something a bit larger. Besides hot drinks, it can keep drinks pretty cold, too, keeping a glass of ice for an evening or longer. Read more

I exclusively use double-walled glass mugs at home so I thought this might be a great travel cup for me. It's good, but it has some issues. First, I thought I was getting something different. There are a number of different options to choose from and I thought I had chosen a cup with a silicone sleeve, but that's not available in the larger 15.2oz size. It really should be because any travel cup should be easy to hang on to and without a sleeve, this one isn't. Especially with how wide the cup is, it's hard to grab an I even have larger hands for a woman. It does fit inside a standard car cup holder though. Speaking of size, there's no way this holds 15.2 oz comfortably. I brew a 10 oz drip from my coffee maker, and it was more than 3/4 full. I had enough room for cream, but I wouldn't have wanted to have much more in there to avoid spillage. I do really like the silicone lid and drinking spout. It closes up nicely to resist spills, but is not leak proof if knocked over. Overall, if they added a sleeve and made the design a little bit taller and less wide, it would be a much better cup. It's also not bad for the price. Read more

The quality of this super-thick, insulated travel mug is excellent and holds up well to our dishwasher. It is SO easy to drink from because of the sippy spout and has not posed a leaking problem for me (so long as you keep it upright, of course). It fits perfectly in my car cupholders and is functional enough that my kids even use it for a variety of beverages beyond coffee. Read more

Be careful with this…it is glass so breaks into a thousand pieces if it hits a tile floor!!!!!! Read more

Cup itself is ok. The inner glass layer in unevenly aligned within the outer layer but it still works, which is fine besides maybe some uneven insulation and aesthetics. The silicone sleeve and lid that comes with it smells awful which makes it difficult to use them, although they do not leak and they do fit well. I even boiled the silicone and thoroughly washed it twice with warm soap and water and the smell does not go away. Might as well not make the silicone parts. Read more

I'm really loving this as an everyday coffee mug. Here are a few thoughts: * It feels very lightweight. I normally drink out of a regular glass mug, and this noticeably lighter in the hand. * It is really pleasant to drink from. I can't stand those sippy-cup style lids so I just use it as a regular open-top glass. The rim where my lips touch the glass is smooth and rounded (the glass folds over at the top) and it just feels really nice. * It gets warm but not hot to the touch. The glass does warm up after holding hot coffee for a few minutes, but it is still cool enough to grab the naked glass at any time. * The silicone sleeve adds grippiness and makes it easy to hold. It's not strictly necessary for heat reasons, but it is a big plus for the ability to hold it confidently since the silicone sleeve part is quite grippy. * The size is a little small. I normally drink out of a slightly larger mug and would like to have a little more room. Because of the dual-layer design it holds less than its overall size would suggest. That's just because of the space between the outer and inner layers. * It came really well packed with a fitted foam chunk around it. I'm pretty confident that if I ordered more they would all arrive intact, which is not always true of double-walled glass mugs. * It feels a little delicate and I'm guessing it will shatter if I ever drop it or bump it very hard against something solid. That said, it is actually sturdier than I expected. * It is dishwasher safe and I haven't had any problem washing it with my other mugs and glasses. The overall impression it gives is refinement and "niceness". I don't think I'd want to use it as an actual travel mug even in the car, because I would worry too much about banging it around and breaking it. But as a morning coffee mug for the home or office, this is nice looking, feels great, and is one of the nicest mugs to sip from that I have ever used. Read more

I really wanted to like this, but there's a taste to the silicone that won't go away no matter what I soak it in. It has an odd, peppery flavor. It insulated just fine and kept coffee fairly warm. But the taste just won't go away. It's a little fragile-feeling, so it might not be that durable. If anyone has tips on getting that taste out, I'd like this, but as it is, I can't really ignore it.

I ordered an insulated mug with a handle and gray lid. The 12oz is a nice size for hot and cold beverages. I drink my beverages pretty quickly so I cannot speak to how well the insulation is for keeping beverages warm or chilled. The handle makes it easy to grip and the lid is a nice feature that makes it portable. Speaking of portability… the mug does fit in the cup holder of my vehicle! Without the lid it looks like a standard coffee mug. I have put it through the dishwasher without any issues. The reason I took off a star is because I do not like the drinking spout on the silicone lid. The lid stays on securely, but the design of the spout feels like I am drinking from a sippy cup.
