The 21oz waterbottle is just as awesome as the 40oz, except it actually fits in my car's normal sized cup holders! (A real advantage on my 6h drive to visit family) The only disadvantage of the 21oz is having to refill it more often than the 40oz.
I appreciate how easy the included V2 lid is to wash as well. That is a nice bonus compared to my original 40oz with V1 lid. I do hope to eventually have an option to purchase a nice straw lid, so I'm not tipping back the 21oz in the car. If it's truly a reusable water bottle that lasts a lifetime, I'd rather not have to buy 3 different life-long bottles based on what application I'm using it in. Maybe just different lid designs?

I love water

I honestly didn’t expect this to be as good as it is. I use it all day, every day.

I have like 10 of these water bottles at this point, all my previous ones are the older designs, and before buying this one I honestly wasn't aware there had been a design iteration since my last purchase. I understand why the changes were made, considering ive had three lids break at the common spot. However, this new design presents a new problem for me. I am a very texture sensitive individual, and the surface of the new lid (ar least for the one I have received) is a rougher texture and it really bothers me and makes me not want to use it as much.
Other than that, the actual bottle itself is the same tried and true insulated metal juggernaut its always been. I had a job where I dropped it off a roof by accident onto pavement and it was still in pretty good shape all thongs considered. Cheers

I purchased the black on black version. The print quality is excellent; it looks great. It keeps water cold. The best feature is the lid. The small top is easy to open and close. As long as it's snug, it doesn't leak. Other lids have been very difficult to clean thoroughly. Pulling the gasket out on other lids is difficult and usually causes damage. The new ltt lid makes removing and cleaning the gaskets super easy. Having the threads on the outside is another great feature. It makes cleaning easy. One last feature, the locking top is helpful when opening the lid, so it doesn't swivel closed on your head while drinking. I will be looking to replace other lids. Great job creators!
