I already have some sucker from Avent (1 + 2) and did some re-ordered to a small supply to have. I am still very excited - the little man finds these also well and likes to drink from the bottle Avent and also comes with the suckers along very well. Confused me only that I have received different sucker (2 packs of 2 slots when anti colic valve (as shown here) and 1 package with a slit. After consultation with Philips, I learned that it is the version with a slit to the newly revised anti-colic valve is and that with 2 slots (as shown here) will disappear soon from the market. However, a difference in quality it is not to give according to Philips.
