On this side it fulfills its functions, nevertheless, I find super great for an infant, I should have taken the smallest model. But considering the price, I'd say I would use the longer, but ...
Also, it collects nunuches, hairs (I wonder how they get far!), I did not it "sucks" fairly quickly finds small discharges, or drooling like cotton does so well, c 'unfortunately.
I use it in all bottles, (so I have several) and I do not regret mostly because it prevents the milk to flow in the neck! So just for that, I would recommend.
