Boon Nursh Straw Cup Conversion Tops for Bottles

These work so well! They do not spill or leak. I have not had it fall from more that 3ft. Probably the most leakproof cut I’ve ever had. I like the fact that I don’t have to buy a whole cup set but instead have the option to buy just the lids. This is economical choice as well as an environmental one. I started with bottles then sippy cup and now this one with a straw. I also have flat lids for storing their snacks. So I feel less wistful and more money on my pocket with the boon system that growers with them. However they are a little tough to drink out of. I tried it because my baby was having difficulty but within a few minutes she was fine. Overall great fit use and easy to clean.

These are great!! Having already had the Boon bottles from my baby registry, these are a perfect upgrade for baby who’s ready to move to sippy cup style! Love that they are a valves straw so no backwash and graduated drinking which allows for baby to not choke on water as they learn. Mostly spill proof though some does leak out of the straw a little but has been dropped on the floor and tipped upside down multiple times and doesn't spill! As an OT mama I love this option in place of a standard sippy cup

These don’t work AT ALL and I can’t believe these can even be sold. Nothing comes up through the straws at all unless you try to perform surgery on them and even still they don’t function properly and you have to suck with all your might. Do NOT buy these.

Absolutely love this lids. Easy to clean. Add some handles and you have the perfect sippy cup using boon nursh bottles.

Love the versatility of this brand with the bottles and sippy cups. I kept one long and one short for my 5oz and 8oz bottles simply by just cutting one of them shorter. The cap is easy to open and close but it does fall out of place from time to time if dropped or forced to close. The straw is a little harder to use because you have to use more suction to get anything, but biting it lightly does help. Bottle doesn't leak unless silicone part is not in place or there's remaining liquid at the tip of straw. Love the quality and durability of these bottles!

Absolutely LOVE Boon Nursh products. When it came time to transition my baby to a straw top, she would not use any other top. We already used the boon Nursh bottle since she was born so when I came across this top and I did not have to buy a whole new bottle was so nice. These are so easy to use and clean. The straw detaches for better storage. Great quality and the seal never leaked. My toddler loved to chew on the straw, and it was stretchy and durable enough to withstand her biting it.

An okay option because we love boon bottles and wanted to transition from the nipple>silicone sippy lid> to the straw without getting rid of the cup parts. However, the straw tops can leak pretty badly and the flippy part is difficult to use. It doesn’t stay latched. The flip part pops off very easily and if that’s not there, and it’s tipped over, or if the temperature/pressure changes, it leaks a lot. It’s a great idea but doesn’t hold up in real life. Three stars because I love boon, the idea is good, it’s easy to clean, and it’s so nice to be able to transition tops with the same bottoms. I’m hoping boon will fix this before my second kid is a toddler!

I bought these a few months ago when I was working on transitioning my toddler from bottles to straw cups for her milk. We'd been using all boon nursh bottles so I thought this was a perfect solution--I thought the familiarity of the bottle would help her accept the weirdness of the different mouthpiece. Nope! I think partly it's just a flaw in logic--she probably rejected it as falling in the uncanny valley, haha--but partly I think it's the design of these lids. The straw did not seem to be easy for her to drink out of, and it would frequently fling milk all over her face and spill small amounts of milk from the straw if it got knocked over. So it was kind of the worst of both worlds: hard to drink out of because of its leak proof design, but also not really leak proof. I also think the straw was too firm to be comfortable for her to drink from when teething (which she... pretty much always is lol). From a parent perspective, I also found these to be kind of a pain in the butt to clean. Even though they're not especially complicated, I found them kind of hard to take apart. Also, as a minor aesthetic note, the boon nursh bottles come in such fun colors--why are these lids so plain?

Todos los peoductos de boon nursh tienen super buena calidad. Ajuste perfecto

Al bb tomar no sale el liquido, los habia comprado por que de biberon sd podria hacer la transicion con estos popotes pero no funcionaron mi bb llora cada vez q lo ve

Es imposible de usar, se necesita muchísima fuerza de succión incluso como adulto fue imposible!

Es bastante duro para tomar, los niños pequeños no pueden hacerlo, además que no cuenta con orificio para dejara salir el aire/gas y esto lo hace aún más difícil.
