GREAT REPLACEMENT
This replacement fits perfectly in my baby’s cup! I was pleasantly surprised at how easy it was to install—it took just a few seconds. The fit is snug and secure, so I don’t have to worry about leaks or spills. One of the best features is that it comes with a cleaning brush, which makes keeping it sanitary super simple. Cleaning and replacing it is quick and hassle-free, which is a huge plus for busy parents. Overall, it’s a great quality product that makes daily use so much easier.

As described
I’ve only used one of these replacement spouts for my child’s cup. He ended up chewing his straw piece to pieces so I was looking to get a replacement when I had stumbled upon this brand. The replacement piece fit right in where the straw normally goes and so far have had no issues at all. I recommend it, it’s the same exact thing as thermos brand straws. For reference: we had the kids thermos, Minecraft design. I wish I could remember the ounces in the bottle but unfortunately I forget. It’s the smallest option

They work
These are a decent replacement for the kids' Thermos cups. They fit and were easy to assemble. They ARE spill proof with the cap closed. However, of the two I purchased, when the cap is open one drips when tipped upside down, the other pours out. Not a deal breaker for me since the kids are older and the cups are only used for water. For younger kids, I can see it being an issue. Overall, I'm happy with them and would purchase again for older kids, probably 3+.

Perfect replacement
My three year old uses a cup we got from a local store and she bit the darn straw off. The replacement is far more durable. I say it's easy to clean, but not everyone may feel that way, as straws aren't always easy. I imagine who ever came up with this got fired because they won't get a lot of repeat business from such a good product. These have lasted 3 times as long as the original parts and I would buy this replacement again, but there's literally no damage to the ones I purchased and my daughter literally chews the straw. She uses them every single day. Great product. Lastly, the little green glow in the dark ring- fits the cups great, but not needed. My daughter uses it as an oversized glowing bracelet... so that's cool I suppose. I imagine that would be more useful to those who go outside at night with beverages or camping perhaps.
