Am dependent on slot sucker for the AR food and that's why I buy the for the third time. Basically a huge fan of Avent, since the bottle even after a long time and umpteen times sterilized are still top. The suckers with the holes appear to be indestructible, otherwise this slot sucker ... the slot widens after about 8-10 weeks, then also tears. Why is that I can not say ... The mouse does not have any teeth, until the 6th month I sterilized, not for 3 months more. Use only the bottle-teat cleaner from Avent, no dishwasher. No matter how, after 8-10 weeks always the same: the slots are torn and expanded. Well, what can I say. Then I'll buy up new ... but shame!
