Ahh one of the joys of parenthood: a hungry baby in the middle of the night! The sound that fills a home with desperation on both the baby and parent. Then this formula maker comes along and boom, a few buttons and bottle is ready to go in a jiffy! In short order the family is back to sleep. Worth itMaking formula overnight is hard, we've been using a bottle warmer to keep the water warm and then mixing on the spot as needed. This mixer takes all the work out of it and is great at those odd hour feedings. The beep on the screen will wake you up (it's a bit loud, I don't know why a silent mode isn't included?!) it is an annoyanceIt assembles / disassembles easy for cleaning. It would be great if it stated the formula part can be washed in the dishwasher. We do it by hand since it didn't say. Just check it is 100% dry before re-assembling it, or you'll get clumps / ruin the dry formula. It is a lot to clean every 6 bottles as recommended, so we use only for the overnight feed, so we don't need to clean it dailyNOTE: Mine arrived broken / used, the box was pretty torn up and parts around the box. I noticed one of the sides was detached as well. A replacement was sent within 2 days, and I had to return the broken one. If you get one that is broken, reach out to support ASAPAt the cost, it is debatable if you should just splurge for the BB brand one, they function similar, and it works better, in my opinion. If this were 1/2 the cost it'd be an easy / strong recommend
