content: Well, no. The mug is stupid expensive, and is an IoT thing. So, while its not something I would have bought, it does what it says, there are no extras to buy. You buy the mug, install an app, pair the mug w your phone, and the mug keeps your beverage at whatever temperature you set. Thats all it is. Nothing else to. uy. it was given to me, Id have never bought it. But it does seem like a well made object and it does what it said itd do.
