This machine is indeed extremely convenient. Yes, u may have to change the dispense spout after every 4 bottles, but u get used to it. It is very easy to set up when choosing ur formula brand to ensure the proper water and powder mix. It take about 5 mins to heat so at night time. I leave it on so that when I go to use it, it's ready!
Very easy to use, makes it easier to get bottles ready and makes baby less fussy getting bottle faster! Very simple to disassemble and cleanse as well. 10/10 used for both of my children
