• I love this product. It is really great for space saving. Jul 11, 2018

  • Love to keep these in our bag for travel or for when we go out to dinner. We do not have to worry about sippy cup because they fit almost all cups. So convenient and easy to clean Jul 03, 2018

    We own a set of these and use them occasionally. They are not as useful as I thought they would be. Good idea but have to be stretched very tight to use. Jun 13, 2018

  • These did not work for me. I found that pressure caused the fluid to rise out of straw and cause a mess! May 14, 2018

  • Love that these turn any cup into a sippy cup! Just be careful if you have a biter, they can bite a bigger hole after a while, they hold up well otherwise! Apr 15, 2018

  • After a few uses, the seam ripped making them unusable. Mar 28, 2018

  • I wanted to love these. I thought they'd be great for travel and restaurants. They work as expected but usually just stay at the bottom of the diaper bag. Mar 27, 2018

  • These are lifesavers! They will literally attack to any cup!! Mar 19, 2018

  • Love this product. It gives my 3yo the feeling of independence when she gets to use a “big girl” cup and loves that she can use a straw with it. Mar 08, 2018

  • Makes life on the run sooooooooo much easier Feb 06, 2018

  • Received these as a gift and they were awesome! Threw them in the diaper bag for emergencies and they always cane in handy! Would definitely buy again Feb 03, 2018

  • I bought one of these to try it out. I feel like I can’t get the lid on right...it’s strange! Feb 01, 2018

  • the sealing always caused the liquid to come back out. It was never functional for us, so I simply got rid of them. Jan 12, 2018

  • Baby hasn't been successful in getting a whole lot of liquid from them yet - but I love that they instantly transform any cup. Saves me from more cup clutter! Dec 20, 2017

  • I love the concept and it helped my son transition into a real cup, but I have ripped a few while stretching them over a cup and they aren't cheap. Dec 16, 2017

  • These are so nice for on the go! Packing a bunch of sippy cups is the worst, these are small, easy to use and they work great! And they come with a little carrying case! Oct 19, 2017

  • Easy to use, easy to wash, packable, durable. Oct 19, 2017

  • These were cool buy im not sure I would buy them again Oct 18, 2017

  • Genius! Great for on-the-go. I toss one of these in the diaper bag or in my purse to have on hand any time! Perfect for impromptu restaurant stops without a sippy cup-no spills, no worries! Apr 09, 2017

  • Love these! Great for toddlers Apr 05, 2017

  • I love being able to use the cups we already have as sippy cups! Dec 01, 2016

  • My only challenge is finding an open top cup with a mouth small enoug to fit the "fits any cup" sippy lid. Otherwise I love the silicone top and color options. Oct 06, 2016

  • I haven't gotten a chance to use these yet but I am excited to try them! Jul 25, 2016

    I love the idea of this, but honestly I did not use them as much as I'd thought I would. (I have the straw covers) May 02, 2016

    These stretch over most cups and don't fall off like some caps do. Lots less spills. Mar 04, 2016

    Love the idea of these silicone toppers but they eventually crack and start leaking with repeated use. Jan 23, 2016

  • These are so great. They keep their seal wonderfully and I love that my toddler is drinking from glass instead of plastic. Oct 23, 2015

  • These are so awesome! I've experienced only good things using these - hardly any spills (though more fighting over color selection)& SipSnaps are the best gift to give to other parents! No complaints. Aug 13, 2015

  • It was really really hard to get this over a normal sized glass at a restaurant. Aug 05, 2015

  • Perfect for on the go or at home! My LO loves that he can use a cup like mommy! May 20, 2015

  • I can only say I regret this purchase because my kids won't use them. Maybe when they learn to use a straw these will be useful. Apr 13, 2015

    Hello Sloan. Have you seen our TOT version for younger children with the sippy spout? That might be the best option until they're ready for a straw. Apr 29, 2015

    LOVE this! I've used this a couple of times so far but it has already proven to stop a mess when baby tipped the glass over! Everyone was very impressed when I pulled it out of my purse! Mar 17, 2015

  • These are very poorly made. After only minutes of use (and I used the bamboo cups from their site) all three of mine tore on the side. A big disappointment. Mar 04, 2015

    Hi Christina, I'm so sorry you've had a dissapointing experience. We will replace or refund your torn SipSnaps! Ironically, our recent round of bamboo cups have an edge that is sharper than most cups causing the tears in SipSnap. Please contact us at friends@sipsnap.com to arrange a solution. Thank you, Michelle Mar 10, 2015

    Ugh. Wanted to love these but they totally leak, especially if you turn any cup upside down...and what toddler doesn't try that?! Jan 23, 2015

  • Love them except the hole to help the flow of liquid leaks all over if not held right. Jan 09, 2015

    Hi Laura, Thank you so much for your feedback! We hear you and we are working on an improved venting system. Jan 09, 2015

  • Super smart and functional! Nice to have in the diaper bag, just in case. Dec 22, 2014

  • So we got these when they were on kickstarter, but are great in a pinch! I've used them over all type of regular and disposable cups and they work. Super young ones sometimes tip it to far and the air hole will allow dripage, so keep that in mind. Dec 16, 2014

  • UPDATE: after using the lid a couple times on a PINT sized mason jar the lid fits loose making it super easy for my toddler to just throw it across the room. Would not recommend this product. Nov 06, 2014

  • DO NOT BUY! These lids tear! After one use, my 1st lid tore. 2nd lid tore after 5 days of use. And I only used the lid on the cups they sell! Also, water spills everywhere! grr. HUGE DISAPPOINTMENT! Oct 28, 2014

    Don't have it yet, still waiting on delivery, but very excited! Aug 25, 2014

  • Gotta have this!! Cant believe ive never seen these before Jun 22, 2014

  • <3 May 21, 2014

  • love the idea of making any cup any size a sippy. For times when you forget sippy cup i would have one of these available in diaper bag. Apr 24, 2014

  • 9 kids and one grandchild so far....I have made an unbelievable amount of purchases of sippy cups. I love this idea! Apr 17, 2014
