Ive had the V1 Travel Mug for some time. It died an early death as Embers like to do. Tried this as a replacement and it’s ok but seems better suited as a kettle than a drinkable coffee mug. The larger capacity is great and really is the only redeemable quality of this particular model. Heating works as expected. But both lids leak.  The sipping lid was awful it would just leak everywhere. The handle lid was a little better but would still leak. Huge failure if you need to use this on the go at all.  Also, I did miss the physical controls on the travel mug. Having to go to the app all the time to adjust settings, check battery, etc was a hassle.
