A must have if you are feeding with formula!! Used one with my second child and will be using the mini with my third. I wish it was easier to empty the water though as my last one there was water trapped so it's not sanitary to store for a second baby.
I love this easy to clean. Makes life easier and makes bottles faster than a coffe maker. I recommend to all mothers and fathers even my 6-7 year olds make the baby's bottle
