what parents are saying
I bought these for smoothies. My daughter loved the texture of the straw but would pull off the top and make a mess. I use the base cup (without the lid) as a cup for her to practice drinking water. (Mar 31, 2017)

Not my favorite. Hard to put on and take off and not easy to clean at all. May 15, 2024
Upon buying, I thought this was an amazing idea however, as soon as I handed the cup with the Boon cover/straw, my toddler had the straw out and water spilling out. This may be good for older kids. May 08, 2023

Hard to get on, leaked and didn’t take long before they got tears in them from trying to put on the cups and we had to throw them away. Love the idea but not worth it. Apr 30, 2023

They are OK. Not totally leak proof. My son's were able to take off the silicone top and manage to get the juice from the cup to bubble out of the air gap on top when using the straw. Jun 23, 2022

Great next step from sippy cups; saves a lot of spills! Jul 14, 2021

These have a learning curve. Make sure to squeeze all the air out otherwise they will leak and explode. If air is out they work pretty well though. Jun 02, 2021

They are ok, hard plastic straw so had to get silicone ones to use. If you put straw through the air hole and leave the straw hole open it has less of the geyser effect. Feb 26, 2021

Ok not going to lie it was hard at first figuring it out but it's great! The cup it comes with is awesome we use the tops on other cups. I just wish it came with more than one cup. Sep 30, 2020

These are great for travel and turn just about any cup into a spill resistant straw cup. We've been using this for over a year and have found that the top has held up wonderfully. Aug 05, 2020

I love these! I keep them in our diaper bag and use them when we forget sippy cups! They have saved us so many times at restaurants or at peoples house. Saved countless spills too! Mar 25, 2020

Did not work great for us. Pressure build up would cause the fluid to come out of straw and cause a mess. Feb 13, 2020

These are a really great idea. My 1.5 year old loves them, as it allows him to use a "grown up" glass with supervision. Will spill, but not easily. Aug 23, 2019

I was so excited about these, they seem great. They are until you realize that if you end up touching and pressing down on the lid you end up with a squirt gun. Something little ones won’t know not to do or will love to do. Also not easy to get on a cup. So disappointed. Jun 27, 2019

These did not work for my son. He figured out if he pushed on the rubber lid water came spewing out... just a mess. May 14, 2019

These are an awesome item to have. Instead of always packing a cup just have one of these in the diaper bag and no matter where you go you’ve always got a cup with a lid! Apr 19, 2019

Love these. A little hard to stretch, and a little learning curve, but work great once you get the hang of it. SO much easier than sifting through and having to clean tons of sippy cup pieces. Mar 23, 2019

I love these! There is a bit of a learning curve- make sure to get air out before pushing down on lid otherwise you’ll have a mess. After at least a year, they have stretched/torn but that’s good time Mar 12, 2019

These have been awesome for my two year. Easy to clean and can convert to any cup. It also keeps spills to a minimum, which is always a plus! Feb 21, 2019

The book snug straw lids work well. I tried them along with another brand and I preferred the other brand more, however these are still useful. Jan 31, 2019

This is great in the to go bag traveling to restaurants in case you forget the sippies or need an easy option to convert cups!! Jan 20, 2019

Fits on many cups for kids. I take these everywhere I have one in every bag. I also have the spout ones to make into a sippy cup anywhere I go with most cups. Jun 06, 2018

Love that they fit the kids Ikea cups! They fit PERFECTLY & the lid actually prevents anything from spilling! I have used these on other kids cups as well and they work just as great. May 30, 2018

This is a wonderful 'tool' to have when you loose a straw peice or a lid and it's supper time. Only downfall is if the baby holds it upside down Mar 01, 2018

So far we like the sippy cup lid. When attached to the cup there's no spillage. Thanks tot he silicone it doubles as a teether for my teething girl :-) Jan 24, 2018

I like that these can fit on a variety of cups but my daughter likes to push the top down so the liquid comes up through the air flow hole. Aug 30, 2017

Tops fit most any cup, great to have in your bag just in case. Spill proof too. Jul 18, 2017

These were so hard to get onto a cup and then the straws would leak all over, waste of money. Sep 23, 2022

Just no. Don’t get this unless you enjoy cleaning up whatever you gave them. Every time they press the silicone cover, it comes out like a fun drink geyser. Straws are hard plastic. Aug 11, 2020

These are not awesome for my kids - they always leak or explode. Aug 05, 2020

My LO 22mo pulls the straw out and has chewed on it. When LO wants more water it’s more difficult than a regular sippy cup to refill. I like that it fits any cup. Unfortunately it didn’t become a fav May 30, 2019

Hard to stretch onto some cups. Straw can fall into larger cups. Doesn't make the cup leak proof but works well on smaller cups to prevent spills from tipping the cup towards themselves May 15, 2018

My daughter only drank from a straw for a long time. I loved that I could turn any cup into a toddler safe cup! Perfect for on the go! Jul 12, 2017

I think these are better than a neutral rating. They travel easily, they go on easily, and they get the job done. Be sure to squeeze all the air out before you put the straw in or it will squirt at u. Aug 24, 2016

Fit well on small IKEA glasses. I like giving my kids the option of a straw with less chance of spills. Straws are short and rigid, so they are easier to clean. Aug 02, 2016

This product is so awesome! I hate digging around the drawer for the pieces of sippy cups that my toddler has unloaded and match them up. I can use this on any cup and it comes in fun colors! Jul 01, 2016
