I was looking for a durable brush (and that's what I got), however it feels like this doesn't clean properly. Also switching from one head to another is a little bit of a hassle, but the idea is good.
Tuttipään puhdistus osa hyvä ja käytännöllinen. Toinen pää hieman turha eikä puhdista kunnolla, liian pehmeä/joustava. Ihan ok setti
My favorite is the small nipple brush
The bristles are durable, and the brush heads are easy to switch between
think it's ok
