Mine worked for a while, but leaks like a sieve now. There is no gasket between the plastic stopper and the metal rim of the thermos. When the stopper is tightened, the plastic stopper is screwed down against the fairly sharp metal rim. Mine is clean and has no visible damage but it leaks like a shower head all around the stopper no matter how tight I screw it down. It's guaranteed for 5 years, so I'm sending mine in for replacement. At least Thermos makes it fairly easy. Just click on the .pdf warranty link in the product description and it has the address where to send it. No RMA needed. I'm not going to trust the replacement to last either, so I'm going right now to order a Stanley.

About how long does it keep your coffee hot? (Do you preheat it with hot water first?)

With tea (a little hotter than coffee when it's brewed) I make tea the night before at about 815, and the following morning it's steaming hot 12 hours later. I have to pour some and let it sit for five minutes before it's safe to consume. Preheating the vessel with hot water first will make the first pour a little hotter, and if you put boiling hot water in before swapping it for your liquid of choice, the liquid when poured in a clear glass will still be mixed phase (bubbles of gas in the water).

My current thermos has a bad design for cleaning the spout/pour section. How difficult is it to clean?

Took a quick look and saw that the 'spout/pour section' narrows down to accommodate the stopper. It might be difficult to access the top of the inside, but I usually will use chemicals to clean my thermos and they would get to everything.I prefer this style of pour where the stopper is slightly loosened and the liquid pours around it. Only necessary to clean the exterior of the stopper.Incidentally I found that BREW RITE does a great job cleaning coffee buildup.I highly recommend this thermos.

You can put in the cup about 6.5 ~ 7 ounces.
