We have owned several different kinds of travel mugs. While the capacity of this mug is about mid-range, the performance is top notch. We definitely recommend this travel mug.This travel mug seems to be double walled stainless steel, with a ceramic coating to minimize any metallic leaching into the stored beverage. We have put ice into this mug in the morning and had ice remaining at the end of the work day. Filtered water tastes as good at the end of the day as at the beginning (with or without refilling the mug).The lid unscrews for removal and the revealed opening is about the same width as the interior of the mug, which means adding ice and beverage, such as filter water from a refrigerator,

Kyocera is a well known Japanese brand for producing hi-tech products. When I saw that they produced a double walled, insulated bottle with ceramic lined interior I thought I try it.First of all, what I like is that it’s not too heavy. I’ve held some other stainless water bottles before and many of them weighed much more with the same volume. Granted, it’s not as light as the titanium ones but those sell for multiples of the price. Also, the bottle keeps the liquid cool/hot as expected and the lined interior doesn’t seem to impart any flavor, but then again, neither does the regular stainless interior bottles. I’m not sure if that’s just a marketing gimmick? The quality of materials,

There is much to like about this travel mug, but one major problem (major for me anyway).First, the good:* The insulation is great. Expect your hot or cold beverages to stay at the desired temperature all days long.* The feel is great. The matte-finished black exterior, the diameter of the mug, and the ribbed shape along the top make this a comfortable mug to carry and use. Operation feels good too. It can easily be opened and closed with one hand.* The capacity is great. I have another travel mug I have been using. Despite this mug from Kyocera having a smaller exterior, the capacity is actually an ounce more than my larger mug.Now, the bad...and for me,

I generally hold Kyocera products in high regard, which is why I ordered this travel mug. (My ancient Kyocera CD player still works like a champ.)This is a very attractive travel mug that avoids many of the pitfalls of others--its ceramic interior means no bad chemicals; it keeps beverages hot or cold, as advertised (I've used it for both); it won't spill when the lid is closed; and ergonomically it works well...except for the lid, latch and spout. As another reviewer noted, those aspects are poorly designed for driving. But beyond that, just using the mug around the house to keep my coffee hot, I found the shape and position of the spout to be really awkward.

This is really a good travel mug. It keeps beverages hot longer than any other travel mug I have owned. Being a tea snob, a ceramic interior is a must. All you taste is the beverage and nothing else! I agree the lid is a little clunky, but it has the advantage that you can open and close the mug with one hand.I have tried the Contigo Ceramic lined mug, the Ello Ogden and this one. Here is the order I would rank them:1) This mug2) Contigo Ceramic lined mug. This is a close second as it has the advantages of lower cost and a sleeker lid design. The lid has the disadvantage that it take two hands to operate. But ultimately beverages do not stay warm as long.3) Ello Ogden.

I’m a big tea lover and following a few stints with metal lined flasks the slightly tainted taste to my posh loose leaf really wasn’t... well, my cup of tea.I researched ceramic lined options with a good travel lid pretty hard and options are pretty limited here in the UK, so looked further afield and found this one. I was almost put off by the reviews stating the lid was terrible and I’m glad I wasn’t, sure it isn’t perfect but far from 1 star!This is a fantastic flask and has served me well in the few months of owning it so far, both in the car and my backpack while hiking/splitboarding. Tea has still been hot 4-5hrs after the brew,

This Kyocera 17oz. Ceramic Coated mug is my new favorite for hot and cold beverages. The mug seals tight and I am blown away with how long it will maintain temperature. My favorite part, it is dishwasher safe! I had other thermo type mugs that worked well but I had to hand wash them. I know, I'm a little lazy at the hand washing of the mugs. I much rather rinse it out and place in the dishwasher to do the dirty work for me.The flip lid works one handed and keep the bugs out while I am using it outside while I work. My only complaint which really isn't product related so I won't knock any stars off, it is a little on the small side for me. I would much rather have 20 to 24 oz size.

First, this is the best looking travel mug I've owned... the smooth matte black finish is beautiful. The cap functions perfectly... locks tightly and pops open with little effort, but without worry of accidentally opening it. Doesn't spill a drop. The design of this mug is perfect.The 'taste' issue that this travel mug claims to resolve by having a ceramic coated interior, is indeed gone. My wife, who is very particular about travel mugs and how they affect her water, gives this mug a big thumbs up.As for it's most important function... keeping drinks hot or cold... it's a 4 out of 5 stars in my opinion. It works well, but I have other travel mugs, particularly a Thermos travel mug,

This tiny-looking travel mug is a jewel of a product. How they manage to keep 12 oz/350 ml of hot beverage hot in this tiny thing is beyond me - but it works every time. The inside is lined with a ceramic coating, keeping any possible metallic taste away from the coffee (a must for this family of coffee snobs). The spout mechanism is dead simple, and just as simple to clean. (The Contigo Twistseal Glaze, a similar product, is also excellent but its spout mechanism is needlessly complicated.) The lid is good at preventing leaking, especially with its simple lock mechanism.The only real downside is that it keeps beverages TOO hot.

Hands down the best travel mug I have ever owned. I drive about 50K miles a year between my work vehicle and my personal vehicle, so I believe I have a good idea of some of the creature comforts required with a travel mug. I can fill this mug up at 8AM and still have hot coffee at 6PM! I am drinking less coffee, because you sip on this slower, since the beverage is hot. The ceramic lining makes this a breeze to clean and the beverage tastes better as well. The lock on the lid is handy if you have ever experienced a flying travel mug. At first I was a bit skeptical of the lid, since the lid lock apparatus is in front of it. This is a non issue since the drink lip is placed in a good position.

First of all I like the that that it fits in my BMW cup holder. Of course, I'm taking for granted that it is a ceramic costed mug. I also like the fact that it has a lock for the lid. I'm having a hard time with flavor. I have tried several mugs, and not one can meet the flavor quality of an open ceramic, or glass cup for that matter. I am nowb drinking my coffee at home in a double insulated glass mug, and use this mug when I have to leave the house and haven't had my coffee. So far it stays closed, and keeps the coffee warm. Lukewarm after 8 hours. I question the reliability of the lid lock. It is hard to close without pushing in the open/close release button. I have had others fail precisely at the release button,

This is a very well-designed travel mug, that looks as good as the pictures and performs as the descriptions suggest it should. It keeps ice water very cold for a long time, and keeps hot coffee very hot for many hours as well.Ignore the review pertaining to the horrible lid design. All you do with this mug is rotate it 30° in your hand and it's completely comfortable and natural to drink out of.Personally, I'd prefer a 100% ceramic cylindrical lining instead of a coating...but Kyocera did a great job on this one. Don't hesitate to buy this travel mug if you want your drinks to stay at their original temperature for hours,

Yall. This mug is it. I've gone through so many coffee/tea mugs. Contigo, Swell, Ello, Thermos, Bodum etc. I've tried different models and different sizes. But they never worked. This is the first mug that does not spill AT ALL. It doesn't open accidentally in your bag. It doesn't take on that weird taste that you can't wash out. The ceramic inside makes my tea taste like tea and coffee like coffee. So far it's been amazing. The only draw back I can imagine down the line is that the lid is a bit complex so it may be come mucky in its nooks if you're not soaking it regularly. But beyond that this mug is it for me. Ill probably only replace it if they start offering a bigger size.

I wanted to make iced tea for the next day. I prepared the tea and let it cool down to room temperature. I then put it in this mug and put it in the fridge overnight. That is a full 9 hours. The tea was exactly the same temperature as when I put it in the fridge.I put iced water into this mug (at 7 am) and went to the beach on a very very very hot day. The mug was on direct contact with the sun's rays and heat. Any other mug would have hot hot water. I opened this around 1 PM and the ice was still just as it was that morning.I write those 2 examples to show how amazing this mug is. I am going to be gifting this to people. It works better than advertised!

The 17 oz. size is pretty small for a water bottle, but perfect for a travel coffee container. It has a lock on the lid. (When you can see the red bit under "push", it is locked.) It is really lightweight. The double wall keeps the outside from getting too hot or too cold to hold and decreases condensation, as well. The lid is plastic and it has a rubber-like seal to keep it vacuum packed for long lasting temperature control. If it matters to you, this cup is made in China. You can not put this in the microwave or the freezer. It does not say you CAN'T put it in the dishwasher, but it does say to clean by hand.
