ContigoSnapseal Byron Vacuum-Insulated Stainless Steel Travel Mug, 16 Oz, Gunmetal

Best coffee mug ever! Keeps coffee hot for ever I love it! Don't know why people are have trouble with the lid leaking, it works perfect for me. If you follow the instructions on putting the lid on it should work fine. So if you're having trouble with the lid you're an idiot!Update- I have had this Tumblr since July 2016. Still using it every day. I love it. I am the type of person that loves my coffee very very hot. This Tumblr never fails me. I also bought one to put cold drinks in. I put water in it with ice in the afternoon one day. Drink half the water. Left the tumbler in my car overnight. Next morning there was still ice in it. But I don't understand why people are having trouble with putting the lid on. If you would read the instructions that comes with the tumbler it explains how to put it on. It's very simple. So stop complaining and read the instructions.UPDATE AGAIN: well it's been 2 years now and I'm still using the same tumbler. I have dropped it several times including on the concrete. It hardly even dents. The rubber around the outside is still intact and almost perfect condition. The lid still seals without leaking. It is so easy to clean. Still keeps my coffee very hot. Contigo rocks!2 1/2 YEARS! This travel mug is never going to wear out! When I clean this I use a brush for the inside and just a damp cloth to clean the outside. I have never submerged this mug in water totally. I soak the lid and soapy water once a week, other than that I just rinse it really well with hot water. Just so you know, the stopper that keeps the coffee from coming out does come off and I also clean that once a week too. At the beginning of March 2018 I bought my boyfriend and one for his coffee. The 20 oz. He goes through coffee mugs like every other month. He has had this one since last March and it's still in good condition. He's very rough on things too. I sent a picture of what mine looks like after 2 and 1/2 years. Still good . Be interesting to see how long this lasts.

Fantastic Coffee MugThis coffee mug is simple, but does it's job perfectly. It is easy to clean, even by hand, but the lid is dishwasher safe so I run it through on the weekends. It fits under my coffee dispenser. It keeps my coffee hot for at least 4 hours (it's all gone by then so I wouldn't know if it stayed hot longer). I can close the lid and throw it in my backpack and not a drop leaks out. The SnapSeal lid is not something I've seen before but it's easy to use, and seals it perfectly. It's also easy to drink out of without some lid bopping you in the face like some of the other mugs.The one and only thing I would change, is they placed "Contigo" on the lip of the lid, so you can feel the texture of the letters when you drink. I thought this was weird placement but doesn't really affect my opinion of the mug. I would have moved it to the opposite side so you have a smooth texture. And then other people would see the brand name, rather than my lips.

I've used a Snap Seal tumblers now for around 3 years. The best thing is that they are truly leak proof. When the drink port is closed, the pressure relief hole is also closed. I have tossed these tumblers in my backpack upside-down and am comfortable doing it. The tumbler's rim is smooth, so I think the lid's o-ring should always seat properly. The drink port seal seats from the inside, so if pressure builds (from hot liquid heating up the air space after closing) it should seal more tightly.You need a strong index finger to open the drink port it with one hand while holding the tumbler in drinking position, but if you don't have a strong finger, you can open it one-handed if you reposition your hand.What I like least is that the top surface of the lid is flush with the rim, so there's no place for one's nose when one tips the tumbler up for a drink. Lots of these mugs are designed that way. That's why the promotional pictures always show the models holding the tumbler in their hand instead up to their mouth for a drink. To drink, I have to tilt my head way back like a chicken looking at falling rain. (I don't know why the designers don't just move the top surface down an inch or so to make space for one's nose.)It seems to insulate as well as other items of the same price range, which is fine for my use but well below the inflated numbers all manufacturers claim. I use the tumbler as a drinking vessel, not a storage vessel. If I don't start drinking, my half-full container of coffee can remain scalding hot for an hour or so. But once I start drinking, it cools down fast and gives me only about 45 minutes to finish my coffee.I think performance numbers and anecdotes that consumers post on the web for these products are meaningless without a detailed description of the experimental procedure. For example, the life time of ice cubes depends a lot on whether the cubes are immersed in water. The amount of liquid in the tumbler and whether you're actively drinking also strongly affects how long it maintains temperature. Just beware while comparing numbers.

This cup is pretty good and keeps the contents hot for a while. It fits perfectly into my cupholder and does not leak in my purse. The lid is easy enough to twist open, and the rubber around the cup makes it easy to hold securely. I like this cup overall and use it daily, but I am not thrilled that the opening that you drink out of is so small and that I can't take the lid apart for cleaning. Other than that, it's a good travel mug.UPDATE: less than a year later, the bottom of the mug is falling out and also the it doesn't keep the content hot for long any more. I got a different brand of cup Zojirushi (spelling?) which is working much better.
