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.

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

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.

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.

This should be standard on all models. Potential health issues with the plastic lids.
This is exactly how they original lids were designed, then they went to plastic for almost all models.The plastic ones have a thin flat gasket and not an o-ring. It's super hard to get it to come out for cleaning. The plastic ones also are made of two parts that are snapped together in the factory. This is NOT a water-tight seal. So gunk gets inside and is a potential health problem. I drilled a hole in the plastic one and gray goo came out. The entire design of the plastic lids is faulty as cleaning is almost impossible.This, though, is all stainless steel. No seams or ways for water to get inside.It also has a standard o-ring that takes a second to remove and wash. This is also a normal industry-standard size.This is not a knock-off, but made by Hydro Flask/what came on the original model years ago and now is a replacement part. I think they sell one or two models with the stainless steel lid and everything else is plastic.This is a mandatory upgrade that will make your flask last 10-20 years without health issues.
