Boon Snug Sip Universal Water and Juice Silicone Bottle Toppers - Soft Spout Conversion Caps with Spill Proof Valves - Silicone Bottle Covers for Travel - Includes 4 Toppers and 4 Cases

bright colors, easy to clean, Good silicone grade no smell at all. I use it for shelf stable bettergoods whole milk. Fit perfectly. I really recommend

Work really well on any kind of a water bottle a little hard to get out at first, but once it’s used a couple times it works better. It will leak a little sometimes after you used it for a while. Would be great for breast-fed babies.

Great product. No more messes with the kids knocking over their drinks. I found that taking the plastic ring from the cap off drinks makes this stay on more snug. Youngest has thrown his bottles and stayed on perfectly. Great for small juice, water, and gatorade bottles. Only issue is found is it doesnt let air back into the bottle making it a little harder to drink but the kids don't mind.

Okay! Yay! So my kid is prescribed PEDIASURE and I've BEEENNNN looking for something that you can just pop on the bottles. She wont drink it from a straw so Until recently we just used the dr brown bottle neck rings with the sippy cup nipple/spout, but with her needing to take lunch to school now I wanted to see if I can find anything that looks less like a bottle. (I had no rush to ween her off, but im concerned her teachers mightve lol) anyway everything was either too small, like for water bottles or too big like for Gatorades and this fits the pediasure 8oz bottles AND she uses it. I saw a review that said these fit the milk bottles from McDonald's so I thought DING DING DING! I did slit the cross/openings with a Knife all the way thru the edge of the top for more flow, less resistance, therefor less spillage. Teach kids to bite first, then drink. They do spill if squeezed or if they don't let air flow in between drinks. Might also spill if not upright, but keeping them around and just swapping the tops out is fast enough so no need to have them on already to carry around. The little carrying cases are great too because I just throw then in her lunchbox and her teachers know how/when to use them. Literally obsessed with these. HIGHLY RECOMMEND .(Adding video of how I slit them a little more open, not a defect)

I really wanted to love these but unfortunately I can’t. They are almost impossible to drink out of and they do not stay on the bottles as well as I anticipated.

To put it simply, it needs an air inlet valve. It's okay for kids that are only sipping. In general, this is everything it says it is! Fits on a typical water bottle (generic water bottle verified) and sports drink bottles (Body Armor verified). It will not spill and the nozzle's cap fits tight over the nozzle. I have even dropped it (for testing) and it stayed on. Also, the cap/nozzle didn't look any worse for wear after the drop since it is all a very stiff and thick silicone piece. So good on durability. The problem is the function as a drinking nozzle! As an adult I test these things to guide my kids. The vacuum force needed to drink is a bit surprising. Lightly biting the tip of the nozzle helps, similar to how you might for a camelback nozzle. From there the problem is the back pressure in the bottle. The cap doesn't have a way for air to go into the bottle as you draw on the nozzle. This causes a vacuum inside the bottle and if the bottle doesn't give, then you're gonna have a bad time. Luckily most bottles do give. Body Armor bottles don't give and it makes drinking from them like lighting a cigar though a coffee straw. So, yes, it's a great cap, but don't use it for chugging drinks like a parched athlete. Cheers!

Great product! Traveling with a toddler was made so easy with these spill proof bottle caps. Also, they are a great everyday money saver. No need to buy expensive character juice bottles—just pop one of these on an ordinary bottle and off you go!!

LOVE, LOVE, LOVE these! I am seriously considering dumping our bottle collection and buying several of these instead! My toddler loves them; they are spill free and mess free. They are easy to install and such great solid quality! They are so easy to clean and fit in my purse, his diaper bag, my pocket. I can literally take them with us wherever, whenever. I no longer need to worry about dragging around an assortment of bottles for my sons variety of beverages. If there was ever a must have product for a mom of littles, it is these!

Puedo convertir cualquier botella en un vasito para mi bebé de año y medio. Ajusta en botellas de yakult, jugo gerber, botellas de agua convencionales. Excelente !!! Traen sus cajitas para mantenerlas limpias cuándo no se están ocupando.

We love these things. They're so handy to leave in the diaper bag in case we need to add a spout to a regular bottle. So far we haven't found anything it doesn't fit onto, it's pretty universal. Yes, it will come off if you pull on it or if your kid manipulates it enough. Or if you squeeze the bottle too hard. But it's more versatile than a straw, and better for the environment. We love this for traveling.

Me gustó mucho q no chorrea, y que son muy bueno para la edad de mi hija (3)

Absolutely horrendous can’t use them at all you have to bite down on the top to get any liquid out! Would not recommend!

cumplio con mis espectativas
