Watched the whole video it looks cool. I agree with the running it through the return pump, it seems like it would be like blendering it up alot.
This would be great if it worked as shown without any unexpected issues for vacations.
Maybe the next Version will include a small display screen and more options for programing multiple feedings a day. Which might also make more complications by adding more potential failure points.
Very high price tag for someone like me, but would be very useful to someone who travels for work alot.
