The concept is truly unique. You can tell it was purposefully designed with your coffee in mind. I haven't seen anything else like it on the market. The customer service was exceptional as well. The only thing that would make it perfect is if the lip part was also ceramic! Because the coffee smell does linger a tiny bit on the aluminum portion but I don't mind.
I was very excited that finally a travel mug was made with ceramic. Although it is ceramic on the inside and does keep the coffee very hot for long periods, the part that touches your mouth is metal. I would say there is very minimal affect on flavor, but I'm still keeping it hot in the mug and pouring into my ceramic mug for optimal flavor. The thin lip design is good and the coffee pours very well, but it is very large and bulky. This was not the revolutionary item I had hoped for.
Love the seal and capacity of this with the matte finish, great lip to drink from and love the coated inside for no stainless taste, I ordered a second one to match my first one. Great for travel hot or anything cold. Does not fit in many drink holder or thermos things and lid needs to be screwed off and back on to drink from is my only complaint. (Two hands needed)
