We have one. I am a fan. With my son we did the boil water, cool it in ice etc. The PP makes it so quickly. Perfect temperature. Very easy to use, clean, filters easy to change etc.
Only con for me was the Watchdog piece on it saying the water has bacteria in it. That made me worry and really wonder whether we should use it. But our daughter has been very well and we have used t since about 3 weeks when my breast milk supply couldn't keep up.
I would highly recommend it x
