My wife and I have had a pair of the JMF-500 mugs for several years and like many others the sipper lids eventually began dribbling. Last weekend I became fed-up with the dribbling and went online to find a customer service number for Thermos Nissan (1-800-831-0745). I ordered two replacement sipper lids for $8.00 shipped and this weekend I'm sitting here sipping from the new lid with no more dribbling. SWEET!

Noticed this mug while searching online for a French press/travel mug. My wife (soon to be ex-wife) and I bought a pair of these about 14 years ago. Used almost every day, they have performed flawlessly. This is a true vacuumed sealed unit and keeps coffee hot and drinkable about 4 hours with the drinking lid, longer if you use the full cover lid. Mine has been dropped numerous times over the years and has survived well.

In all this time, there are only two drawbacks I can think of. It's diameter, although very stable, it won't fit cup holders in many vehicles. And, if run through the dishwasher, a small amount water will sneak through the little hole in the bottom cover. Not a big deal, but it can dribble out on you while dinking (it can be removed to dry off).

Unlike my wife, this travel mug has remained true to me all these years.

This really keeps hot things hot, cold things cold, just like it ought to. I have a 45 minute walk to work every morning, I fill this with hot tea before I set out, and the tea is still hot by the time I finish the mug full, about 30 minutes later, even on mornings when the air tempature is in the low 30s (F). The only thing to watch out for is the sipper lid is very, very easy to mis-thread. It seems to go on fine, but it isn't a tight seal, whereupon it becomes a dandy dribble cup, which drips not on your chin where you would notice it, but farther down. One cold morning I suddenly realized the cup had soaked my right pants leg. Funny to read about, I know, but embaressing at that particular moment.

I can't leave well enough alone so I cut the handle off my mug, cleaned up the edge, machined a steel caribiner flat and silver soldered it on. I also covered it with safety orange reflective tape and I can always find my mug. No one else would want it. It's been great for almost 10 years now.

As for the problem of the drinking lid becoming a dribble cup, I took the o-ring out of the lid and noticed one side is flat and the other is curved. The curved side is normally out but I found that if I flipped it over so the flat side is out it quit leaking.

My "Nissan 15.9-Ounce Travel Mug/Food Storage Jar" Kitchen; ...each
LEAKS out around the seal between the drinking lid and the mug. The problem occurs when the coffee cools and condensation forms inside. The problem is getting worse and I've had coffee leak all over me many times. I've tried drying the seal and screwing it tighter and nothing works. I suppose this mug may be defective and will seek a replacement or refund.

After getting fed up with cheap travel mugs (leaky tops, limited ability to keep coffee hot), I splurged on the Nissan mug several years ago. Hundreds and hundreds of commutes later, I can't say enough good things about it. The only days I'm disappointed are the ones I forget my Nissan mug at work and need to make due with a lesser mug. It is true that the base does not fit in most car drink-holders; not a problem for me, but could be a deal-breaker for some. Also, I don't use the sipper lid, so I can't speak for that. But if you're looking for a rugged, leak-proof container to transport your 15.9 oz of java and keep it hot for hours, you won't do much better than this item.

I drive truck for a living and was always buying coffee in a paper cup. I found I always got heartburn as I had to drink it so fast to enjoy it hot. Then I found this mug. It keeps it warm up to 6 hours. Great... no more heartburn. I ended up buying one for my wife,and my boss bought one for himself and his wife. The only problem is, that as the cup gets older, the seal starts to leak. My first cup is in the cupboard it leaks so bad and I now use my wife's cup. Lately it has started to leak also. I wish you could buy replacement seals.

I am shopping for a new travel mug as I just left this 7+ year old mug at my kids school and I can't wait for it to turn up somewhere. This mug is absolutely the best. 7 years and no drips, unless the gasket is not seated correctly. I just wish I could have an even bigger mug so I can take more coffee with me in the morning. I'm looking at the bigger Thermos, but I loved this one so much, my decision is a tough one.

Unfortunately, I've had it seven. For the past year it's been dribbling into my lap. I wish I could fix it, cause I really liked this mug 'til it started leakin'. It fits the large cupholder in my truck, it's fairly splashproof, and I can even put on the solid lid and carry it in my motorcycle saddlebag. Sip-lid leakage seems to be a common problem, so I'll probably shop for an alternative.

AARRRGH! I lost my Nissin mug after thirteen years of perfect service. Dents and dings new O-ring and all, it's gone. I wish I had a picture of it to show the abuse that it withstood, and it kept coffee warm for hours. Now I have to get a new one. For those of us that like things to serve their purpose and don't care about fancy flashy lights and gizmos, this is the best mug ever.
