This is my 4th Ember mug and I was excited to try this product. I spend lots of time in the car transporting kids to and from school, so the travel tumbler is useful for me. A huge disappointment is the tumbler doesn’t fit in my van’s cup homier. (I have a 2018 Honda Odyssey). It completely defeats the purpose of having a travel tumbler and I’m forced to hold it in one hand as I navigate interstate traffic. The tumbler works great otherwise and I’m happy with the 3 hour battery life, but not fitting in a cup holder in a standard mini van is a huge oversight on Ember’s part.
