SYACOT Auto Spout Lid for Hydro Flask Wide Mouth Water Bottles, Replacement Top Spout Lid for HydroFlask Wide Mouth 12 oz 32 oz 40 oz, Chug Cap with Flexible Handle,Big Nozzle

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.

After Hydro flask, sent me two replacement lids, both of which continued to leak and were difficult to keep clean, I ordered these. Excellent replacements, better design, MUCH easier to clean, they fit standard Hydro flask water bottles.

They are the perfect next step from the lids with straws. They don't leak, My kids take them to school in their backpack and they work perfectly. They also have a lock so they wont pop open. My kids LOVE THEM!!!! I just ordered 2 more sets.Update.....Sorry to say but after a month or two of every day uses, they break.... The buttons come off, the lock brakes and the whole thing just comes out. The lid won't latch and you can't put it back together. They are just not made strong enough. I can't get a refund now, but definitely do not buy if you are using it for every day.. not worth it!!! So very disappointed...

Lost my 64 oz Bubba wide mouth lid and have been searching for one that will fit because I just love that water bottle. I’ve bought 2 other wide mouth replacement lids that were fitting awkwardly, leaked, or just took a lot of effort to test on. Although this particular lid does fit a little snug, it’s been the best one. It screws on better than the other replacement lids and doesn’t leak!

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.

I bought several of these last year for various water bottles. Those were great. I needed a couple of replacement have daily wear and tear and reordered a few weeks ago. Two of the tops have already broken to where they won’t close at all. Disappointing that the quality changed.

I have been searching for a faster way to open my hydroflask during quick breaks when working out. This auto spout has a super fast trigger button that pops the lid open to a large chug spout. I can quickly and with just one hand open, chug, and shut the lid within seconds. I am not a fan of straw or suck spouts and prefer being able to drink regularly and the opening of this lid allows me to easily do so. The trigger button also slides to lock so I can throw it in my bag and not worry about it opening up.The material is sturdy and strong. The quality rivals that of the actual hydroflask brand lids. There arr n o sign of cheap manufacturing like visible molding seams, locks or dents, or extra plastic. This lid is sleek and smooth and beautifully matte finished. I ended up buying one for my son and he loves it as well, he plays ball and loves that he can grab a super quick drink when he has very brief break in the game and not have to worry about spilling.Best auto spout on the market!

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.
