“An insulated, all-in-one appliance” is going to be more along the lines of your traditional sous vide appliances in terms of pricing…not sure Anova wants to try to compete in that market.
All everyone wants is a basic scheduler - it’s up to the individual to determine how long their particular vessel will take to come up to their desired cooking temperature (through experimentation). Ratio of ice/water, how well insulated the vessel is, volume, how well sealed it is, ambient room temperature and even elevation will all contribute to the warming ramp-up time.
Basic feature, not a lot of excuses as to why we never got it (closing in on 3 years that customers have been asking for it).
