Great
Love the new straw design for the internal side. They use kind of a rubber silicone material that holds tightly without coming loose requiring your to open your flask up and reattached the dang straw! So that in itself is such a huge improvement that this is a top notch product! No leaks and fits great, highly recommend!

It is as described
I didn’t have any problems with the original. It had fallen and hit concrete so the original top broke as it just happened to fall lid first. Just as good as the first still leak proof and no problems with the new fit.

Great replacement
I have bought several times due to I keep dropping or it falls off my work truck, it fits the water bottle great, doesn’t leak, I like how it comes with two straws and clean. Only thing is that I say is the do brake easy if they fall from a work truck,

Great lid
Great lid It's easy to clean and fits my bottle well from the same brand. It's a bit on the pricey side for a replacement lid but that's not much a hurdle for me. It's quality in its mold and I haven't had any leaks.

Great replacement lid!
Great replacement lid for my water jug, only problem is that sometimes it creates a vacuum and the water starts coming out of the tiny rubber hold under the straw while it’s down. Otherwise it works great! Easy to clean, it is made well, fits perfectly!

Old lid broke from a fall
I looked to find a replacement lid for a 128 oz drinking container that is taken to work everyday. Well a fluke of a fall the drink container was fine but lid had a crack and if laid over it would leak. So I found replacement and all is fine till it takes another hit as construction has no limits
