Review: Perfect toddler cup - We were in search of a cup with as little plastic as possible that would actually work for a 1 year old to use. These have been great. So many other stainless steel or metal cups still have plastic handles or plastic surrounding the body of the cup. I appreciate that this one does not. There is of course plastic on the lid, but whatever. You do as much as you can. One component that drew me to this cup was that the straw is stainless steel instead of plastic or silicone. The cups barely leak when tipped over. I’ve shared a photo of the cup almost upside down in our sink. You can see only a very small amount of drops are coming out. There is silicone for the tip of the straw, but cleaning with Castile soap Somewhat regularly has helped us avoid mold growth on the inside of the straw, as well as the soapy taste left from washing silicone in the dishwasher. I would prefer plastic free, but concede that the silicone tip is safer for young children drinking from the straw, and majority of the liquid is still coming through the metal straw. Our dogs got one of the cups while we were gone, and while chewing on the silicone tip, they clamped the tip of the straw down. It looks like we will be able to reform the straw to be functional, but in the meantime, we were pleased to find that one of our own metal straws was able to fit in the lid. Our straws are much smaller then the one that comes with the cup (standard straw size), but the seal around the straw is still very good and does not really leak. The cups also come with a handy attachment for traveling where you can seal off the liquid completely. These also work fantastic with no leaks. Overall an impressive product for adult adults or children.
Review: THESE ARE THE BEST KIDS STRAW CUPS OUT THERE!!! - I am not exaggerating when I say these are the best kids straw cups available! They are DURABLE!!! I have had mine for 2 years and they are in perfect condition and used daily with my 3 and 5 year olds. Often for us, my kids chew the soft silicone straws down long before the cup has needs replaced. But the beauty of this product is that you can replace the silicone straw covers as often as needed! And they sell packs of the silicone straw tips separately and in all the colors so you can purchase and replace as often as needed! They are not leak proof but definitely leak resistant. I love that they come with a thermos lid so you could pack cold fruit cups or hot soups in your child's lunch. I honestly could go on! Such an amazing kids product that lasts!

### ⭐⭐⭐⭐ Cute, but a bit heavy - best for advanced toddlers!
*by B***️ on April 1, 2024*

The cups are so cute, very well made - stylish too! However, they are a bit heavy and may be a bit much for younger toddlers or those that are still in that 'throwing' phase! Even a three or four year old is constantly dropping things, so I wonder how the cups will look after a few months. The cups do leak with the straw inserted, they only appear to be leak-proof with the vacuum-insulted tops. Overall, versatile and recommended. The cups do well with drinks or used to maintain the temperature of snacks.
