とても静かです!
I purchased this because I have a newborn in the house that can’t be put down. Using knife becomes too dangerous. I would like to slice things like carrots, cucumber, and onion with this. The noise is so small it doesn’t wake the baby (I have a vitamix blender which is 10,000 times more noisy!).
Moreover, I look forward to making baby food with this when he turns 6 months.
