BoonBoon Snug Spout 3pack lids - Boy,

I love those! Really good quality and my baby finally knows how to suck from it water unlike other bottles and cups where he couldn’t figure it out. I recommend it!

LOVE IT !! IT IS TOTALLY HELPFUL, I RECOMMEND IT

Leaking, waste of money.

Not a good alternative

Good quality..

My son hates it lol. He is picky though and takes a while to take to new things. Oh well lol, they are are great quality and super cool! And if he never takes to them, at least I have my own spill proof wine glass now haha

I would highly recommend these! At home we use these with those colourful plastic cups from IKEA, but these work with pretty much anything on the go at restaurants and cups/mugs/glasses at friend's homes. So easy to use (though not recommended for arthritic hands as you need to be able to stretch these quite a bit to fit them over the cup - my mother in law isn't able to use these). We've been stopped countless times by parents asking where we got these. They are super easy to clean and fairly durable. In one of the 3 lids, my son had chewed a larger hole back when he was still teething a little and so one of the lids has a slightly enlarged hole in the top so we use that one for thicker liquids like smoothies. I sometimes think how many spills I would have had to clean up per month that these lids helped us avoid, ha! It's well worth it. Stop reading and add to cart.

These work fairly well with the Munchkin cups we have  Munchkin 40300 Five Multi Cups . Unfortunately, the green one started getting small tears along the seam after only the third use. The other two have held up well after multiple uses. Pet hair and fluff stick to these like crazy since they are silicone. Easy to wash. Spill-proof, but not necessarily free from water mess. My toddler has learned that he can make water shoot out through the air hole if he tips the cup upside down and presses the top in. Munchkin 40300 Five Multi Cups

Hard to get onto a cup, but totally worth it because that’s what makes it leakproof. I use these with the munchkin cups. Because the air vent hole is so tiny (leakproof!) sometimes you have to pull on the sippy part to get some air back in, or pull the side away from the cup for a minute. Basically, my kid will suck the air out of the whole contraption while he’s drinking...but, again, totally worth it for the no spills ever.

I really love these. You need to put them on and make sure they and the cups are both dry, they wont stay on if even the slightest bit damp. Love that my kids can use glass and nor plastic. My kids can take the lids off, but dont unless the cup is empty... I thought it would be a disaster with my 2 year old, but hes actually good with it. I bought two sets. Of the two I have one that has a small slice/RIP in it, which wont allow us to use it with certain glasses without dripping. I'm not sure if the rip was faulty product or our fault. Regardless, I love them and so do my kids. We dont need more, but i would totally buy more if we did.
