Zak Designs Kelso 15 oz Tumbler Set - Perfect for Everyday Use, Stylish and Durable Drinkware

GM: Doesn’t leak when knocked over. My kiddo likes straws so it’s a win win for both of us. I had a coupon to redeem so that was nice! I’ve tried many different cups & brands, but this one has been my favorite so far. They are also VERY easy to clean. The whole straw comes out out for cleaning.

Amber C.: Very nice cups and love that there's several different colors and designs to choose from and that they come in double packs the only complaint is after a while they can end up leaking or dripping from the air valve and the inside straws cannot be in a dishwasher or will end up melting at the bottom or top of straw and if they are shaking too hard or thrown a lot straw can pop out spilling liquid out of cup but this is one of the only Cups I've found that my autistic for your old actually will use and drink out of so this is the second pack I've purchased and will probably purchase more also when a drink is sitting in the cup sometimes the liquid can force itself to Outer top of straw and spill over or fill with liquid and when you pick it up come sloshing out but my toddler is rough with them so maybe it's not that way for everyone who has used these but they do seem to last quite a while even after being thrown and washed in a hot dishwasher and that is good enough for me they have the lasted anywhere from 7 months all the way to over a year before getting more enough to replace so I would still recommend these cups to others

Adam Andrews: I love the design and that they hold a decent amount of drink for my kiddo, however the downside is still the same as any sippy cup I’ve purchased lately. They leak. My almost 2 year old has this crazy fascination with throwing literally anything and everything. While yes we are working on trying to get him to stop, it would still be nice at least to find a sippy cup that doesn’t leak even when he doesn’t throw it around. These ones, they leak every time it gets laid on its side. Standing upright, no problem. No leaking when it’s like that. But any time they are on their side, there’s a literal trail of water.

Donna Hileman: My daughter learned to drink from a straw around 8 months and she loves these cups. Not that she can walk she Carrie’s it around with her by the straw. She drops it all the time and it hasn’t broken so I’d say they are pretty sturdy as well as relatively leak proof. The only time it has leaked is if the straw is tilted to the side while being held upside down and this happens if say it’s thrown or dropped and land on its lid after the straw hits the ground first and even then it’s only a drop or two that escapes. Lid comes apart in 3 easy pieces to clean and it’s easy to put back together as well.

loco287: These are great! Perfect for the intent. Still leaks a little bit. So not total leak proof. But it's to be expected.

Sturdy and durable. Not uncommon to be dropped, tipped, turned upside down. Thrown down during a temper tantrum. These are awesome and the kids love the. A 15mo old toddler and a 3 year old that will occasionally use it, but prefers the kids Yeti water bottle now days.

Eric Xu: My toddler likes the look of the cup but doesn’t like that it’s harder to suck and he can never get all of the milk out

Sam: We've tried Munchkin 360 cups and Oxo straw cups and this one is my daughter's favorite. The straw in the cup looks wide but the water flow is slow and controlled which is perfect for toddlers. My daughter tried it once and is obsessed with it. Great to increase water intake.

Anvino: Cute design it hasn’t washed off or faded yet but i imagine it will eventually. The lid is tight and the straw will not spill out water. I found the pull a little straining but both my kids have no problem and continue to drink from their bottles.
