Do these have a 100% flat bottom without any ridges? Need it to work on my Norpro coffee cup warmer. Thanks a million!!

No, it is not totally flat. I don't know if it would work on your warmer or not. I keep re-warming mine in the microwave. It has a ring on the bottom with the middle part up some towards the cup. Hope this helps!I love my cups, but I use them in my microwave!

No, unfortunately there is a ridge. The middle will not sit flush with your warmer.

Sorry to be so long getting back to you. Just a low ridge as I recall. It could get knocked off because there is no room for a flange since it sits so close to the coffee. I got mine for camping but gave it away when I opted for high end instant, which is simply less hastle when camping. Still love my Melitta at home though.

Yes, they have plastics inserts with ridges. Other phones need a smaller end. I like them very much.

No, they do not. Don't waste your money like I did. The seller's answer is either ignorant, or hustling to move product. These will NOT hold a cup.

It doesn't have ridges. It's completely flat. And it doesn't have turn-off feature either. Plugging/unplugging is the only thing that turns it on/off.

They are flat on the bottom. They do have ridges that go up into the pan/pot, but that doesn't affect anything.

Very small ridges. I just replaced this piece after 25 years of using the first one. The old one became too smooth to work well, but the new one I purchased has the ridges.

Mine have never popped out. Are the cups the normal size? I did see some on sale that were more rounded on the bottom so that may make a difference

No. They are plastic on the bottom. These keep the coffee warm without heat. Thermal carafe, like a thermos.

Not per se, but there are raised ridges, for lack of a better description, that create indentations on both ends that allow you to grip. When you use these the lids are on top. This pic is a bit misleading. I used it like a regular cooler with the lid up.

I have bought a number on line and they are all flat bottom. I have the rounded ones, bought elsewhere, but they are smaller.

I cannot answer because the cup (s) we ordered were not cone shaped. Have you contacted the seller? They were very responsive to our questions.

Haven't noticed that. I will now check....Okay. What I see is they do wobble on the counter, but they do not wobble at all on the cup, which is where the use is intended. I love the 2 I bought. My main reason for getting them was the lovely porcelain, which does not absorb anything, and the wide base for my larger mugs. I am not at all disappointed.

These mugs are not perfectly flat...there is a slight indentation on the bottom. We just dab each mug with a dish towel before removing it from the dishwasher.

Yes ma'am...They are flat...but I have NO experience with glass top ranges. I can't help you with that one, LOL. But so far, I love them because they clean up EASILY.

I am not currently looking at one, however there are no ridges so it is 'flat' in that regard. But, if my memory serves the bottom is very slightly convex so it is not 'flat' as in a perfect plane with the surface it would rest on. So, explained another way the bottom is very slightly domed up, but with no ridges.
