asobu Ultimate Stainless Steel Ceramic Inner Coating Coffee Mug with Double Walled Copper Lining Insulation,12 Ounces (Baby Blue)

I highly recommend this mug. I have owned it for 2 years and expect it to last forever. I like my coffee piping hot. OK fine, like the family says, boiling hot. This is ceramic mug is perfect. I like how my hand fits in the curved handle - I have been through a few mugs, turns out my arthritic hands don't like the rectangle handles. I like that the edge of the mug is very thin and fits my lips for pleasant sipping. The ceramic coating makes it easy to wipe out the stains. It comes in variety of colors; I chose the color of the Rocinante mugs :-). The plastic lid with rubber guard is sufficient and effective but it is not meant to be spill-proof. With the lid on, my drink stays hot for a couple of hours. With the lid off its about 35 minutes, enough to finish before it gets lukewarm. Some have noted the sliding part of lid gets loose. This is not a deal breaker because I sip with the lid off. And if you are careful when rinsing the lid it will not get loose. Avoid taking the sliding part of lid apart too much otherwise the tiny gasket will get lost which causes it to become "loose". This is not a travel mug per se - it will not fit in a car cup holder unless you have very wide cup holders and a open notch near the bottom for the cup handle, however it fits in my Toyota Tundra cup holders with that middle insert removed. I have dropped this numerous times (note arthritic hands) and no chips or dents! Good quality and fit for purpose!

Keeps my drink cold/hot for a surprisingly long time compared to other ceramic mugs. Doesn’t leak, I like that the rubber band is removable and the design is not complicated so it’s really easy to clean.The only thing is that it’s a little awkward for holding in a single hand (I might just have small hands)So I would like it better if it had a handle (:

I'm very pleased with the features and function of this cup. The ceramic lining makes a very noticeable difference when drinking hot coffee.. no metallic after taste. The lid is simple, seals great and is easy to drink from. Keeps hot drinks hot a long time and the silicone ring on the base keeps polished granite countertops from being scuffed. I recommend this one.

First off, I was disappointed when I opened the box and saw I was sent a coffee mug stamped with 12oz 360ml instead of the 16oz 490 ml Ultimate mug that was shown in the listing photos. To be sure I tested the volume and it held 12 oz. I was really hoping to get the 16oz 490ml one that was pictured. Also the measurements provided in listing do not match what was received. Listing shows 3.5" wide x 4.75" tall, whereas I measure 3.375" wide by 4.5" tall. I already have a ceramic 14oz mug I wanted to replace with an insulated glass or ceramic one. I have some excellent stainless surface travel mugs, one with a nice handle but I do not like the taste steel imparts and I prefer glass or ceramic. This mug definitely looks nice, holds temperature well and has a ceramic coating over the steel core. The half-round handle makes the mug tend to tilt to side as you hold it. An ear shaped handle would be better. The lid is serviceable as it helps the beverage maintain temperature and seems splash proof while walking around or driving. If you hold the mug upside down or it falls over on it's side, liquid will seep out even with lid slider closed (unlike my two travel mugs). But for what I will use it for, sitting at my desk or even car trip, that is not really a problem. You must hand wash and be gentle, with no dishwasher, microwave or freezer usage. Because it holds temperature well, no reheating in microwave is not of any concern. Very solid desirable mug, I just would have preferred to receive the 16oz 490ml Ultimate mug shown in listing. (BTW, their shorter, wider cork bottomed one did not interest me as much as the Ultimate)

I have ceramic lined pots and pans, which I really like. So I thought I'd give this mug a try and I'm so glad I did. It's very nice with a thick durable ceramic coating. It keeps my coffee hot even without the lid. Some reviews mention chipping. My guess is they are not gentle with a spoon. These need to be handled in the same way as my pots and pans. No metal to ceramic clanking. Just be gentle and you will love this cup

Sort of meh about this cup. I'm keeping it but my search for the perfect coffee cup continues. As shown in the photo, the lid is not the claimed "tight". Liquid freely dribbles out if you knock it over. It's too wide (3 5/16 inch) at the bottom for my cup holder so it's not really a travel mug. It is not dishwasher safe which is annoying. It keeps coffee warm and the lid helps with that. The ceramic liner seems good although it has that odd design of the steel being exposed on the outside of the lip. The handle is functional. Like I said, meh.

This was my third attempt at finding a ceramic-lined mug that I could brew tea in without a metallic or plasticky taste. Mug #1 worked great until I tried to clean it - the white ceramic stained badly and my attempts to scrub it eventually ended up chipping it. Mug #2 was the only one I could find with black ceramic, so my staining problem was resolved. However, it had a unique lid design that, while ingenious, I ended up not liking. The mug was smaller than I wanted to begin with, and the lid took up a lot of room inside, which made matters worse. This one, mug #3, is great! I don't know how they did it, but even though the ceramic is light-colored (off-white/beige), it doesn't stain and the tea residue wipes right off. And while the mug walls are not as thick as either of the other two I tried, it keeps my tea plenty hot. I did replace the lid because the one supplied has a sliding closure that got in the way, but I could have lived with it if I didn't already have a replacement handy. The only improvement I would suggest is the handle - it's strong but not particularly comfortable.
