small cup is 150ml, my glass is 230ml, 300ml if you want more water like refill in water bottle... the bottom compartment can remove to refill tall water bottle...
only 4 button,
first one is safety lock for 45 70 85 and 100 degree water, 25 degree no need press this unlock button
second button is change temperature, again is 25 45 70 85 100 degree can change
third button is produce water, when producing water you can press this button anytime to stop the water....
fourth button is change water quantity to be produce... 150ml 230ml 300ml, it will produce this amount of water then stop automatically, other dispenser you need to press and hold like siao, actually i like this more
all button is glass touch sensitive button, not physical button like seers tend to broken after some times
i think this heating method is like those nespresso coffee machine... the sound also same, just this one cannot put the capsule
the con of this is no continuous pour (i think is because this instance heater the fresh water storage only 1 liter tank, after draw some water you need wait the main filter to refill automatically back the machine)...
for cooking and other water still use the direct outlet at countertop...
this one need wall mounted as it cannot stand on itself coz is only about 10cm thick...
my local supplier has something similar but cost much more, was planning to connect to Aquaphor water filter
