I find it EASY to wash thanks to its wide neck (you can enter the sponge in it). It also goes very well dishwasher safe. Ets the bottle comes with a mini brush to clean the wheel and valve.
The assembly of the valve (wheel + stem) is VERY EASY, you just have to engage the well 3 pieces to prevent them from falling during feeding (it only happened once at the beginning because I n ' had not supported asez strong).
The stem includes a navy blue thermal sensor that turns purple if the milk is stuffy and hot pink if it is very hot. It is a practical detail for moms like me who have no feeling in the hands (due to illness).
During the feeding, we see the valve move, expelling the air outside. The tétéine is flexible and wide which is ideal if mom is breastfeeding or if baby is in transition "in-bottle". bottle-fed babies also appreciate that broad side which allows good tongue and nipple position that deforms the suction mimicking the natural movement of the maternal nipple.
I tried other bottles but my son refused them all. Since q'il has those FAREWELL colic and smiles hello.
