Isosteel VA-9556Q 25 fl. oz. Double Walled Slimline Vacuum Flask, Screw Stopper, Quickstop System - Single Hand Pouring, Insulating Plastic Drinking Mug - BPA free

Love this. Keeps my coffee warm for hours. Good for probably two large cups of coffee (like large mug size). The push button release to open is easy to use and seals well - no leaking on mine. Insulation is not a problem. Taken mine hunting (20 degree outdoor) and still hot 7 hours later. But light and small enough to take anywhere.

Drip free as long as spout is tight. The cup will drip a little when removed if you don't get it dry after using for 1st cup. Keeps my coffee hot for a couple of hours. Still warm enough for me after about 4 hours. I just rinse with water and there's no stain or build up so far. Made in China.

Thought this was German made but bottom of bottle says 'Made in PRC for ...'. Started to have cap issues right off the bat. Had to trim the silicone seal to make it work, that go us set for a while. Now three years and a lot of use later, the quick release topper end has split and now the quick release does not work and no amount of trim to silicone will fix it. The thermos is still usable, but replacement parts are not readily available, so I cannot recommend this thermo to others.

I've used it 3 times and the stopper broke. I handwash this thing. Worst purchase in a while. I'm really bummed about it. Buyer beware!

Would be great - if not for the stopper. I saw the questions about temperature. When first got it - water from heater 175F. Sealed it and left for 12 hrs at probably around 65-70 degree ambient air temperature. When I rechecked - 147F. Pretty good! Filled the thermos with coffee on a trip. Poured out fine initially. When I went to re-pour, I screwed off the top lid to have coffee spill in my lap. Not that much about 20-30ml. The stopper was leaking. Took it home and repositioned the two part stopper. Continued to leak. Sending it back. Too bad. BTW- Isoteel of Germany - made in China.

I have used quite a few thermoses like this one. I really like the vacuum seal and the pour stopper. BUT...this one is the best one I have found. I have poured my hot coffee with creamer into it at 6am and had it still steam when I poured it at 4pm. It keeps the coffee hot for longer than any thermos I've ever used. It's my best friend now.

My hubby loves his thermos! Best gift ever!

Works great. I find if I preheat with boiling water this will keep my coffee hot over 8 hrs. In an 8 hour day I have 2 breaks, one in the morning and one in the afternoon. I'll have a cup at both breaks. The morning cup is steaming hot, by afternoon it's a bit cooler but still what I call hot, hot enough you can't gulp it down. When I get home any coffee left is still pretty warm and drinkable. You will get a couple of drips from the pour spout after you close it. To keep this from being a problem just re-tip the thermos over your cup after closing the spout.
