Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count

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

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.

I thought there was a manufacturer issue with the straw because my toddler, who is proficient at drinking from straws, couldn’t get any water from this. Then I tried it myself and I could *barely* get any water to come from the straw. If an adult can barely get it to work I don’t see how a baby could. Will need to look for a different straw cup which is unfortunate since we used boon for bottles exclusively and have a lot of them.

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!

Great! Toddler loves it, great design. I love that I can take the baby nipple and screw on the straw lid. Easy to clean as the straw is larger.

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 to transition my little guy from him Boon bottles to a sippy cup with minimal waste. I wish all bottles had this option so they could continue to be used. Will recommend time and time again!

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

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

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 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.
