Thermos Nissan 14-Ounce Leak-Proof Insulated Travel Mug

I use this for bringing coffee on the train and even ride my bike with it in my backpack. Very water tight and also keeps coffee nice and hot.

I've been using this Thermos Nissan 14-Ounce Leak-Proof Travel Mug for about a month. Since a coffee would cost me about $2/day the mug pays for itself in less than two weeks. It keeps my coffee hot and fits in my car cupholder. It has been leakproof (I just fill it, screw down the top and throw it in my backpack) and rugged (can't imagine how I might break it). I have no use for the large handle but..

I have been using this mug for over 5 years. It is absolutely durable. Mine has traveled extensively, both on daily commutes and around the world on trips. It is 100% spillproof, and can be packed with confidence in a briefcase or suitcase when full. The lid can be turned 1/2 turn to sip hot coffee slowly, then resealed. As long as they make this mug, I will never use another!!! There is no substitute and I have tried dozens...

My wife got one of these 10 years ago. She is STILL using it today. The only reason I'm buying another one today is so that she will have TWO of them for her long commute/workday! It is utterly leakproof (I usually pack it sideways in her lunch bag), totally shockproof, incredibly easy to clean, keeps coffee hot for hours (sometimes, if she makes tea for her car ride home, it's still hot the next morning when I clean it and refill with coffee!), and clips onto anything thanks to the carabiner. There is simply no better insulated mug!

I've had this mug for a few years now. Still going strong. The only truly leak-proof mug I've ever owned. The top screws down tight just like a thermos. You simply loosen to drink.

Only two problems. One, there's really no good way to tell at a glance whether it's closed or not. So.. sometimes you hook it to your backpack, forget to check if it's closed and are dribbling coffee down the hallway.

Two, changes in pressure, whether inside the mug or outside (think airplanes) can make it very difficult to open.

The carabiner loop is a nice feature.

They probably say you can't put it in the dishwasher, but you can. Sometimes water gets in the lid, but the lid breaks into two pieces and it's easy to get out.
