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.

Still used daily, works great.
This was a Christmas gift for my daughter, and she uses it every day. Quality product, arrived quickly, and would buy from this seller again.

Upgrading my cap
Love these bottles and that fact that I can still buy replacement caps.

Works great!
I replaced the regular lid with this, and I love being able to drink without unscrewing the whole lid.

Great for kids but can leak
The grandkids need a top that doesn't open completely. We love these and will be buying more. It does sometimes leak but way better than when they knock one of the ones with the screw cap over and the cap isn't on it. They love drinking out of this one.

perfect alternative for your hydroflask
I swapped out the standard mouth cap on a standard mouth bottle to this lid and noticed it lined up with no cross-threading or leaks. I used the flexible handle to carry the bottle clipped to a bag during a short hike, and the seal held liquids contained even with bouncing around. Cleaning really didn't require any additional effort as a bit of water and a quick brush were sufficient for any residue inside the cap.

Worth every penny
I’ve been using this for around a month now and it works better than the reviews I saw. I’ve had no issues with the tab breaking, it fit perfectly with my 18oz hydroflask, easy to clean, and no leaks while it’s closed.
