My 1.5-year-old child doesn't want it at all.
He/she is very scared of it when he/she hears it, so we manage to use it with force only twice

I bought this because I didn't want to have disposables. Very good construction. It had two front nozzles, one for the beginning which was very gentle and one for later. The music it has is somewhat useless although very good. I would put the front nozzle in the sterilizer and it didn't suffer any damage. Very easy to use. Be careful when opening it for cleaning. It has small rubber bands inside to seal it airtight, so if you lose them (like I did), it won't work. (The solution to my problem was very simple, I just found a rubber ring that fit.) Good purchase.
