Do anyone know why the nipple would collapse as he's drinking. Also what is the notch for on the screw ring?

You're twisting the the ring too tightly so the valves don't work, thereby creating a vacuum.

Not really sure but I am sure that the old nipples and the nipple "holder" that you screw on will not fit the bottle. I believe its a bit wider.

No, the pop-off lid and the plastic insert are part of what makes up the screw-off top. You screw off (sorry for the redundancy) the entire top to drink. Hopefully that explains it.

You would have to buy the nipple ring. The center of the cap is not removable.

Seems odd that it falls out. Is the bottle too big? Maybe not in all the way? It seems to operate like what you might see in a bar when pouring shots. It allows only so much out before you need to turn it right side up again and pour a second time. Mine works great and I love it!!

I threw that away. The only use I could see for it would be if you were going somewhere and you didn't want the liquid to get in the nipple. I suppose you could put powder formula in the cup and use the plate with the screw lid and then remove it when you add the water. Again, we threw that piece away. Hope this helps.

I would like to know the same thing. I checked really close to see if it is one of those quick release switches, and it does not appear to be for that as it is all one piece of molded plastic. I thought maybe it somehow controlled the flow but when I used it, I would engage the button while drinking and I did not notice any difference in the flow. I would like to get an answer from Condor on what this is for.

The best answer is that it is NOT sharp. Not sure how rounded it is but it is not a problem drinking out of it. Nothing sharp about the edge.

Have only had this problem with drinking glasses getting stuck, one inside the other. Maybe instead of hot water just rap gently with a wooden spoon on all sides of the neck while gently pulling the spout. Cover with a cloth just in case of breakage. Good luck. Hope someone comes up with a better idea.

It is just a seal for travel to ensure no leakage. You can't drink when the circular piece is in.

You have to manipulate the "nipple" part to open up the holes; pinch it toward the top. I also poked a skewer through the holes to ensure they were open. Hope that helps!

Not at all! We had had for 6 to 7 months and not 1 problem at all. Our son did bite through 1 nipple because we didn't pay attention that he was teething, but that is what can happen with any bottle!I give it a 9.7 out of 10 because I wish they had more schemes other then the two we have found available. It would be nice to have different patter or colors to tell if one is a juice cup and one is a milk etc.I say buy it, you will love them!

I'm sorry I don't know. I've had to switch to advent bottles. My LO and I could no longer breast feed and found she didn't need a nipple to stimulate breast flow. She is much happier on classic flow.

I had the same issue at first. I still don't understand what the top cap is for. To drink out of it, unscrew the whole top. Where you pour the water in is also where you're supposed to drink.

My Pinzon got stuck in the closed position too. Placing it over an uncorked bottle and working the handle up and down immediatley fixed mine. You should also know that the original Penguin lasts (almost forever). Now that the mystery complany Pinzon has taken over, they are made to fail, especially if you use them often to open the plastic (composite) corked bottles. I took one of each apart and the downgrades by Pinzon (plastic interior parts) are a real disappointment. They last a while, but nothing like the original Penquin.

It unscrews. It took me a while to figure it out because the others lift off. If it gets stuck, gently use the part on top that closes the drinking opening like a handle and turn it to the left - remember this little saying - lefty loosey - righty tighty. It never fails me. Enjoy it.

I loved this mug until I tipped it up to finish my drink. Liquid came out of the seal area when lid is screwed on. At first I thought that I failed to screw the lid on tight. Had my husband try and he also had liquid dribbling down his chin. Everything else about the mug is wonderful.
