EXTSUD Kids Cups with Straws Spill Proof, 6 Pack 12 oz. 304 Stainless Steel Unbreakable Reusable Water Drinking Tumblers with Lids and Sleeves, BPA-Free Colorful Stacking Sippy Cups for Toddler, Adult

Overall I like these kids cups because they are durable, provide a straw and sippy cup option, are dishwasher safe and they have the color coding so each kid knows exactly which drink is theirs. I made the assumption that these cups would be like my YETI and other stainless steel water bottles and would keep the beverages either cold or hot. They do not! For me this was half the reason I purchased them because my daughter wants her water to stay cold...so disappointed in that regard but all other features are nice. Also they do a good job not leaking if they are upright, but if they are thrown or turned on their side or upside down, they do leak

I ordered this for my grandchildren after seeing it at my daughters. The lids fit very tight. The kids would drop them and they wouldn’t leak a drop. I liked that they were stainless steel instead of plastic. But when I received my order, I was VERY disappointed. After hand washing them, I went to put on the silicone sleeves. One tore in half immediately even before I had it on the cup. Then the lids fit very loosely. Every time they are dropped, they pop off and spill everywhere. I wish I knew why my daughters are so great and mine are total duds. Ordered from the same site. :(

These cups are very nice for the money but not spill proof unless completely sealed. They do not prevent spills when the straw is in place.

Instructions say to boil all parts before use. DON’T boil the plastic lids! Figured it was fine as we have done this with plastic baby bottles, etc. in the past. Nope. Our lids are now all warped and don’t fit the cups at all. Didn’t get to use these cups with the lids. However, we really love the cups and straws.. all very durable and the kids like them too. Had to take the silicone cover away from my 3 year old but he doesn’t mind the metal straw by itself. I will be ordering another set so we can try again with the lids, washing them by hand this time.

I like the cups but they leak because the straw is smaller than the hole for the straw. Disappointed! I was hoping for a leak proof cup with a straw.

These cups leak and are they are poorly made. The rubber toppers melted in the dishwasher. There are too many small parts, not practical. The rubber piece on the top of the straw is the perfect size to get lost down the drain. Don't be fooled buy the good reviews!

My 2 yr old loves these. Only issue is that they still spill/leak when he lifts them to his mouth to drink due to the straw hole. Straw also just pulls out instead of having a little stopper like adult cups do. Overall they are sturdy and easy to clean.

These are great for my two grandchildren, both under 5. I like that they will not leak when tipped or rolled and they have straws. I also like the thermal lining that keeps things cool or warm. Colorful. Reasonably priced.
