Nuby Replacement Silicone Spouts, Colors May Vary, 2 Pack

Comment: This will make my 3rd shipment. These Nuby spouts are better than the old ones. The Nuby sippy cups (that these fit) have the newer spout on them...except for the cheaper version that you find packaged alone usually at Target and maybe Walmart? Those still have the old cheaper Nuby spout. These seem to hold up much longer. My daughter was not a chewer but my son it wouldn't matter what sippy cup it was he would chew it. I am glad that these are BPA free so I don't have to worry as much about that! Also, I test my spouts out before I give them to my kids. To make sure that there are no leaks just fill up the sippy cup and if any liquid comes out through the spout from gravity then it gets tossed. Otherwise I end up with wet kids. Great price too!

Comment: I was glad to be able to replace the spouts on our Nuby cups, rather than replacing the entire cup. I will not do so again, however. These replacement spouts have lasted less than 6 weeks. Our 20 mo. only uses these for milk, so only 2 or 3 are used per day, for short durations, and we have 6 in rotation. It seems to me like that is not excessive use, but, like many kids, he loves to chew these spouts. He had to chew them at first to get the milk out because the holes were so small and as other reviewers have also noted, the air release valve is inefficient causing the spout to get sucked in. This occurs whether the milk is cold or warm. I was really hoping these would last, but they did not, so I won't be reordering.

Comment: I absolutely love these replacements! My son will sometimes bite the silicone causing them to leak so now that I can just buy the replacements and not have to throw away the whole cup it has made things so great! Thank you!

Comment: The new spouts are NOT like the old spouts, I just bought new cups and they don't let enough air into the cup, so the nipple inverts into the cup when the child is sucking liquid from it. So every few seconds, the lid has to be removed to allow air back in, the nipple returns to normal position and then lid put back on. My son doesn't really like them anymore because it is too hard for him. I compared his old with his new and they changed them, WHY?!?!?!?! They were great before.

Comment: This sippy spout fits the adaptor for Klean Kanteen water bottles - allowing you to make them into a sippy cup w/ the least amount of plastic possible. The fit is very tight and so far no leaks. The spout is made of silicone (although the packaging does not state the grade of the silicone) and is soft. Liquid does pool a bit in the valve and can be a bit harder to clean (my reason for not giving it 5 stars).
I wish that Nuby, and other brands in general, would state the width of the opening of the base of the product so that it would be easier to know if spouts/nipples would fit on other products. Plus, I really wish the grade of the silicone was clearly stated on everything.
Food grade silicone is a synthetic rubber which contains bonded silicon (a natural element which is very abundant in sand and rock) and oxygen. With BPA and Pthalates a concern in plastics, this silicone spout is a good alternative.
