Yeah I am not sure it's worth $30 at the end of the day, but the quality and coatings are excellent. Definitely a cut above the usual suspects like Thermos, etc. I use it every day so it's worth it to have a nice one IMO.
I have this one from Zojirushi for the car and it's expensive as well but extremely easy to clean and worth every penny:

It works too well sometimes, I have to let the coffee cool down before I put it in the mug or after a 3 hour drive it's still way too hot to drink and I have had zero coffee
I can't really be upset about that though haha.
