Great lid.
Was a little worried if these would be good quality or not but they are great. The feel very sturdy and perfectly fit my 40 oz hydroflask. The seal is perfect and the plastic is nice and thick. I am sure these will last a good long time.

Love Love Love!
This seems to be a very well built cap. I've been rocking it for a couple months now. Spring action is pretty forceful so I just make sure to have my finger behind it when opening so that it doesn't break and fly off. I'm not saying to change it though!! I like it. The handle seems rugged and secure. It fits on my 64oz Hydroflask. I have Ice cold water again! Thanks to this well sealed cap. I haven't had any issues this far. Well worth the money. My only complaint is that it's a little loud when drinking from it compared to just the open bottle. But I love the cap.

1 yr Later ... it's worth it!
Update (October 2025) ** Have used these pretty constantly since the middle of LAST YEAR. Only now am I thinking of replacing these ... because they are starting to wear out. Both lids are not latching all the way 100% of the time, and water leaks a bit from the rubber rings under the lid. For over a year of pretty regular use, washing, and using daily, they held up well for only being less than $16.00. Original Post (2024) **Water tight and works well even after a few months of use. **Doesn't screw as tightly down as the name brand. ** Give it an extra squeeze while putting the lid on and it will hold well.

Spring breaks after a few months
The very thin metal wire that springs the top open always breaks off after a few months. I've already had three break on me with no unusual use. This latest break off I was lucky to find the "L" shaped part that is normally visible sitting inside my cap after it broke off. Cheaply designed and completely avoidable if they uses a slightly heavier guage wire for the spring mechanism.

Works good! Really like these covers
Doesn't leak. Able yo lock and unlock the spout. Perfect, better than having a twist off lid. Easy, push the button and the lid pops up. Push the cap down and it clicks in place. Slide the button up and it locks the lid down so no unfortunate mishap. Perfect. Definitely buying more for my wife's containers.
