W&P Porter Insulated Tumbler 20 oz | No Metallic Aftertaste Ceramic Coated for Water, Coffee, & Tea | Wide Mouth Vacuum Insulated | Dishwasher Safe, Charcoal Terrazzo

I would rate this 20oz tumbler 4.5 stars. However, I erred on 5 since it is the best tumbler I've found on the market. It is thoughtfully designed in every way.PROS:- CERAMIC COATING! Coffee tastes so much better in ceramic than stainless steel.- Large capacity while still fitting in the cup holder!- So easy to clean! Every single part of the lid disassembles, making it super easy to clean every crevice, and easy to re-assemble.- This keeps my drinks super hot! The heat retention is so good that I started using this as my regular mug at home, not just when leaving the house! Even without a lid on, it will keep my coffee hot for at least 30-60 minutes. With the lid, obviously, it's much longer!- Leak proof! Honestly, when I saw the lid, I did not expect this thing to be so leak proof. Then, I brought it to church with me where I was singing in the worship team. I put my mug under a seat in the sanctuary, and stood up on the front platform. During service, I gazed across the room and saw, to my horror, the cup had fallen over. I thought for sure that the coffee would have spilled all over the low-pile carpet. But alas, it did not, and I didn't have to admit to anyone that I brought coffee into the sanctuary haha. Which leads me to a con..CONS:- It's top heavy and easier to tip over, especially when placed on a surface like low pile carpet. This is probably a feature of it being wider at the top than on the bottom, in order to make it fit in car cup holders. Thank goodness it's spill proof!- The ceramic started chipping after only a few uses. It's minor, but seems to be multiplying every time I wash. I never put it in the dishwasher or use the abrasive side of the sponge. To be fair, I am yet to meet a ceramic coated travel mug that does not have this problem.I think this could be the perfect cup if it was made into an 18oz without the asymmetrical width, and had a more durable ceramic coating. But until then, I will always be using this cup because it's so far the best around!

Perfect size, durable, washes easily, leak proof, keeps my coffee the temperature I want.

I use this cup with a stainless steel straw instead of drinking from the cup itself. Only for water. Just a warning, the interior is coated in white, and the white coating has scratched off from regular use after 2 weeks. If you don't use a stainless steel or glass straw, then you're probably ok. However, I wish they would have left the interior untreated so I don't have to worry about strange chemicals leaching into my drink over time. Otherwise, the rest of the cup is great. I like the exterior softness of the silicone sleeve.

Just what I was looking for! No metallic taste in my coffee. Enjoyable to drink from with the thin body sides. However, it’s a bit of a mess trying to drink from the actual lid (too thick and it’s not comfortable with a hot drink- why do they do that??) I hate lukewarm coffee that I get after a short time in my ceramic travel mugs. This one kept my coffee decently hot after a few hours sitting in the car. Holds so much more coffee than my 12oz even though it’s not that much larger in size. Recommend!

Love this cup. Can use with hot or cold drinks, and it truly does make a positive difference in the taste of your beverage especially if you cannot finish it quickly and it just sits.-Also, This should go without saying but since it’s ceramic coated ( the cup under the silicone is metal) do not use any abrasive cleaners , or bottom rack of the dishwasher, I would recommend investing into a good reusable bottle brush, and using a mild dish detergent . Best bottle brush I’ve used is the Owala bottle and straw brush 2-in-1. it’s dishwasher safe so you do not need to replace it unless it becomes damaged.

Bought because of ceramic coating. Scratched on first use with the spoon I used to stir my coffee and now get worse with every use. Too expensive to not last.

Good value for the money.

i splurged on this cup because i wanted to make sure i had a good insulated cup for work (but its also just super cute lol).the insulation works great, it stays hot for my whole morning and warm the rest of my work day, if i dont finish my coffee early.the only things i have an issue with is:- the coating is starting to come off on the edges (shown in pic) + ive only used this maybe for around 10 days- there is a strange taste and smell after a few uses, and i wash and soak this in water after every use… ive even tried to get the smell out with vinegar but that didnt really work.- the cap is very hard to clean, mostly just underneath the opening contraption, theres not really a way to get any soap under there so its starting to look grossi like the look of it but im just worried it wont last, it was pretty expensive for just a travel mug..**EDIT - i was able to clean the bottom of the lid properly! i found out you can just snap the cover off to clean underneath, i didnt try this before bc i was scared to break it but it was easy to snap on and off! :-)**ANOTHER EDIT - soo, i’ve been using this cup for hot coffee at work for a couple months now and it has developed a disgusting taste. I looked inside while cleaning it and the ceramic coating has started to come off.. i probably wont be using this again bc im worried it maybe is coming off into the coffee and im sure its not great to consume that lol so just be aware!this one can be a good long time use cup :/
