Lifefactory Sippy Caps for 4-Ounce and 9-Ounce BPA-Free Glass Baby Bottles, 2-Pack, White, LF135009C6

These caps are good for toddlers. I love life factory bottles so they are good to use on the bottles after the nipple top phase. The only issue is that if my toddler drops the glass bottle.....the bottle itself holds up but this cap will break. Otherwise these are good.

I know people say these caps break easily but I’ve owned them for quite some time and I’ve had no issue. Both my toddler and infant use them. They drop these bottles all the time. Only one issue is you do have to open the cap up frequently and remove the rubber and retighten it so the flow continues. Not a big issue for me

These are terrible bottle caps. I have ordered them 5x in the past two years (that’s ten caps), and every single one has broken. They haven’t gotten lost. They’ve cracked and become unusable with the slightest drop (my two year old, like most, isn’t tall.) Amazon, kindly, has replaced 1 set, but of course, I had to call customer service and go through that rigamarole...would rather the caps simply not break. We do have slate floors, but they are only sometimes the location of the fall. Almost any drop on any floor save carpet can crack these caps, but the bottles survive. In fact, we’ve only broken and replaced ONE bottle compared to the TEN caps. And that’s because it fell from my shoulder height while I was carrying my son over the slate floor. Needless to say, it’s pretty pitiful how easily the caps break. I suspect it’s because the plastic is BPA free, which I appreciate and is one of the reasons why I keep buying them. The other reason I’m beholden to this awful cap is because my two year old latched on to this particular bottle brand as his lovey— cute except now I’ve spent $45 in caps alone and need more so he can sleep tonight. Please send me more, Amazon. And please redesign these, Lifefactory— they are the worst. I wish I’d saved and photographed each one: they break almost the same way in a spiral every time. I even finally bought another color (kale) to see if it was intrinsic to the blues. Nope. They all do it.

These helped my child transition away from the bottle nipple. Though, broke easily when hit against a hard surface. If your child likes pouring water out of their bottle, they will like this. We weren’t able to figure out the anti spill gasket so didn’t use it.

Love that these go onto the 4 oz and 9oz bottles we have, but they seem to crack easily as we dropped the bottle from not very far up and the plastic cracked. I purchased more, hope they don’t continue to crack :/

I researched these caps for several months before actually taking a chance and getting them despite all the negative reviews. I have had no serious problems with them. I’ve had the caps for over a month now and they have been washed over a dozen times, no issues! In my experience all sippy cup lids/caps “leak”. For the most part these do not unless my child leaves a little liquid in the spout of it. I’ve had bottles laying on their sides or upside down for quite some time and no leak issues. There is a rubber type valve in the cap, some reviewers have stated that they removed it I did not. This is what helps the caps NOT leak. When you take the rubber valve out of the plastic cap the top of it has a small slit in it. While washing them before 1st use, I pinched the opening of it to kind of unstick it. When I put it back together I sucked through the cap to see if it had an easy flow & it was perfect, my toddler has no issues. It might make more sense if you purchase them. All in all, I’m super happy with my purchase.

These are great for the life factory bottles. My toddler has no problem with the transition. So far no leaking

My daughter loves their bottles been having a very hard time taking bottle away. So I ordered 2 sippy caps. I had to take the plastic cover on the inside out I even tried it since my daughter was crying and having a fit. Nothing was coming out. So, I understand her frustration. Then my daughter dropped the her bottle while getting out of the car she was closer to the ground so I didn’t understand why it cracked. In all the time I used these bottle 1 have only had one break she through it out of dads truck and another time I left on top of car.Now to see if the second sippy cap last longer than the 1st one, one day in and it broke.That didn’t happen both broke with in to weeks we love life factory. Stay hating that I have to buy another set since my daughter loves her bottle so much that it the only way she been able to leave the baby nipple on the bottle.
