Good buy!
Very nice! Closes tightly. Easy to take apart and clean. I like that the softer parts are red so that mold can’t hide.

Just what I was searching for
Cap fits my 21 oz Hydroflask and does not leak when the spout is closed. I was not able to confirm before I ordered that it would fit my size bottle so I'm posting a couple of pics so others can see that it fits. Packaging includes clear instructions for how to fit the straw to the cap, and an extra straw is provided as well.

Great addition to the water bottle
Works great and makes the bottle so much easier to use. Easy to quickly disassemble and wash in the dishwasher. Sturdy and nice looking. Would buy again.

Almost Perfect
You can't use it without the straw and you have to use the straws it comes with or it will leak, even if it seams like the same size. But other than that it's a great replacement for the usual cap. I know it sounds simple but I love it because I'm always trying to find ways to get myself to drink more water and the flip straw rather than having to unscrew the cap makes a huge difference in my water intake.

It’s a must for your bottle.
I need to replace my cup lid. Great for me.

Leakproof
I needed a lid that was leakproof and so far, this one is. I don’t use the straw feature, and the flow is on the slower side. I prefer this because my kids also use this water bottle.

Does what it says (not for warm liquids though)
Works well, does not leak but DO NOT USE WITH WARM LIQUIDS, just cold drinks

The smell of the red silicone
For those who are sensitive to smells this cap is not a good choice. It has quite a strong smell from the red silicone. I cleaned it many times and left it outside, anyway it smells.

Worth the money
Love it, great attention to detail. It comes with two straws, you cut it to decide the length so it works for all bottles that fit the lid shape. The red tab at the bottom can be used to hang the cap on the side of the bottle so its easier to fill up without pulling the entire straw out.
