Thermos Nissan 14-Ounce Leak-Proof Insulated Travel Mug

I've been drinking from one of these for years. A few months ago I lost mine and replaced it with one we had lying around that was plastic on the inside instead of stainless--I knew this one would not keep my coffee as hot, but I thought perhaps I'd gone overboard and could get by without replacing my Nissan Stainless mug. After a few months, I recalled the lesson I'd learned about these mugs years ago: because they keep the coffee so hot, for such a long time, YOU DRINK LESS COFFEE. It sounds kooky, but I've been overwhelmed by this discovery twice in the last decade. (Here's how: consider that when you take a sip of coffee, you get the smell, the strong flavor, the steam on your nose, and the hot beverage warmth in your mouth. As this coffee gets colder, you will discover that your sips become gulps... because you want that "hit" of the hot beverage and the flavor. Not only are these gulps less satisfying, but even die-hard coffee lovers understand that too much of a good thing means nature calls more frequently, urgently, and your tummy might start to roar.) If you would like to drink less and enjoy it more, you will love the Nissan Stainless Mugs.

Pros of this particular mug:
-The top is ingeniously designed. Lots of thought went into the shape and how well it conforms to your face when you drink.
-It's leak proof, folks. I think some who have reviewed it poorly in this regard have mistaken the claim: it's leak proof if you seal the lid. As for whether you spill it while you're drinking, nobody can account for how one person drinks. If you set it on the car seat or hook it to your satchel with the included clip-thingie, or if you turn it upside down while it's full, NOT ONE DROP will escape. HUGE improvement over the model I bought seven years ago.
-Easy cleaning, rubberized grip and handle, 5 year warranty--this is not your granddad's thermos.

The only thing I'd presume to be a con, in all fairness, is that it looks a bit ostentatious, spacey. However, the handle is nice and makes the whole mug fit very naturally in your hand.

Invest in this mug: you might even save on coffee or trips the bathroom in the long run, and you won't spill a drop unless you miss your mouth.

I have four of these mugs.

Pros:
- Keeps coffee hot for a very long time when sealed.
- Doesn't leak.
- Durable.
- Carabiner makes it easy to clip onto backpack.

Cons:
- A little inconvenient to clean.
- Nissan unresponsive about replacement parts.

Tips:
Make sure the lid is screwed down snugly, but not too tightly. You want to form a complete seal to prevent leaks and retain heat, but the seal gets tighter as the contents cool and shrink.

Don't fill past the raised metal fill-line on the inside of the mug. If you overfill the mug, some liquid will be pushed up into the threads when you screw the lid down, and you won't notice until you tip the mug. (It's easier to see the line if you fill it beneath an overhead light.) If you think your mug leaks, you've probably overfilled it.

If you fill it just right, you don't even have to stir your coffee. Just add your sugar, cream, ketchup, or whatever you put in there, seal the lid, and shake the mug to mix it. (I've never been able to do this with any other mug).

When you wash the mug, remember to remove and wash the silicone rubber o-ring. The lid is hollow and can be pried apart with a spoon for cleaning if some liquid seeps inside.

If you wash the mug in the dishwasher (Nissan recommends against this), remove the plastic base before (or after) washing to remove the water that collects in there.

If you lose the gasket (or cut it on a knife in the dishwasher like I did), I've found these to be suitable inexpensive replacements after a lot of hunting around: 228 Silicone Rubber O-Ring 70A Durometer, Burnt Orange, 2-1/4" ID x 2-1/2" OD x 1/8" W, by Small Parts Inc.


The best I've found!   August 11, 2001

In 27 years as a bus driver, I have drunk a lot of cold coffee, and spilled a lot more, from many brands of so-called insulated, leakproof coffee mugs. I first found this cup at the Brookstone store in the local mall and thought the price a bit steep but it is without a doubt the best insulated cup I have ever owned. It was absolutely leakproof and remains so after three years of daily use. This cup is also manufactured under a "high vacuum" process that maintains the temperature of the contents better than any other I have used, bar none. The trick is to "season" the cup...fill it with HOT water, let it sit overnight, empty it out, and then fill it with your hot coffee. It's good for 4 to 5 hours at a very drinkable temperature! Season it with ice cubes and water for cold drinks. The other handy feature of this cup is its handle.It is wide-spaced from the body of the cup, allowing you to carry your briefcase, purse, or umbrella in the same hand as the cup. In my case, buses have no cupholders and the non-slip handle fits easily over the sun visor, keeping my hot coffee within easy reach. The only two drawbacks to this cup are (1) the price tag and (2) after the contents of the cup cool off a bit, the lid can be somewhat difficult to remove due to the vacuum created...a small price to pay for the only vacuum insulated cup that REALLY IS what it says it is. I wish I had a commission for each of these cups bought by my fellow drivers!


Best coffee mug I have ever tried   June 25, 2002

My fiance spent a lot of time looking around for a coffee mug that would work for me, and he picked marvelously! The best features of this are the most important ones: convenient size for car drink holders, holds enough volume to be worthwhile to bring it with you, keeps coffee very hot for a long time (I can fill the mug and cart it to the gym with me and 2 hours later, drink it and the temperature is perfect!), is comfortable to hold AND DOES NOT LEAK when closed!! There are very few products I love the design of enough to write about, but this is one of them. I know I sound like a hired Nissan advertiser, but it really is worth the [money]. I use it everyday.


It Really is All That   October 18, 2005

My friends are getting bored about how much I talk about my new travel mug. I spent days researching it because I had been disappointed by so many coffee mugs in the past. I bought many of the metal-type mugs from Starbucks which were very leaky, prone to dents and generally messy. I even spent around $30 for a Japanese thermos (Hitoichi? the one with the elephant logo) that I thought for sure would be my last; however, it leaked too, even though it had two caps! This Nissan mug I can vouch is totally leak-proof and I feel perfectly safe putting it in my bag on the go. If the mug isn't leakproof, it's probably defective and you should return it. No worries there.

Usage note: A previous review mentions that you can take apart the lid into three different parts. This was very helpful information! I was tentative at first, but you can just take the rounded tip of a dinner knife, wedge it between the top and bottom part of the lid and the top will pop off. It's good to wash the insides, or else a damp smell will lend itself to your coffee. Take the same knife, gently stick it under the rubber ring which will also pull right off, and there will be no coffee dried in any hidden crevices of your mug. The mug resists getting the weird taste/smell (if you keep it clean) much better than any of the other mugs I've tried.

On the value it lends to everyday use: the mug holds approximately the same volume of coffee as a medium sized coffee from Starbucks. I can see why people would want it to hold more coffee, but an added bonus to making your coffee everyday is that you can treat yourself to better coffee beans. I used to spend $10-13 each week on coffee at Starbucks. Now I buy a half pound bag of coffee beans which lasts me at least a week or two (depending on whether I just take coffee in the a.m., or have more in the evenings). I buy a half pound of coffee ($12-$18 per pound) from Peets Coffee or Stumptown Coffee. The coffee is incomparably better than the regular drip at Starbucks, but it's still cheaper than buying your morning coffee everyday. Buy expensive coffee and feel frugal! Awesome. Or just buy the regular beans, it would cost even less!

The coffee does stay hot and flavorful in the mug. In fact, sometimes it can even be a little too hot and I just loosen the lid for it to cool down.

If you get this mug, I'm sure you'll enjoy it!
