Here's what customers have to say
The product received very positive reviews overall. Customers praised its ability to maintain hot or cold temperatures for an extended period, the leak-proof lid, and the durable construction. Many found it suitable for everyday use, travel, and outdoor activities. However, some experienced issues with leaks, difficulty cleaning the lid, and the paint or color fading over time. A few felt the temperature retention was not as effective as expected. Despite these drawbacks, most reviewers were satisfied and would recommend the product.

Try before you buy. It might would if you are Superman.
Yes, we have the cap installed correctly, red gasket flat side up, concave indentation side down. Worst lid cap I have ever seen. It takes first place. YouTube reviews never tell you this lid is a pain to take apart. Getting to the closed red spot, which blocks liquid, isn't easy, but it is doable. But sliding it past that point to the left to unlock the cap takes a very strong grip and power. You don't have much to hang on to either. Twisting it back on isn't any easier. It's almost like you are going over a plastic hump, a end stopper at the left of red close position. Maybe we got a bad lid, I don't know. What I do know. We can't use this thing. My wife can't twist it off, and I can just do it, this is insane. You really despise cleaning this thing. Just going to buy something else. I'm not even going to buy another lid for this thing. I am not a happy camper. I suggest you try one in a store first, especially if you are female as I purchased this for my wife. Unfortunately, we had to order an in-store delivery because it wasn't in stock, so we didn't try to take it apart before purchasing.

Functional! Beautiful!. . but the cap sucks
[This review was collected as part of a promotion.] The bottle is exactly what I wanted, primarily the capacity, size, and shape. And the engraving is cute but I dislike the cap it came with. It's hard to unscrew without having to futz with the closing mechanism afterwards so I have replaced it with the cap from my old hf. Much better.

Is this the same bottle as the 20oz with the wide mouth, the only difference being the cap?

The top cap will not release. Seems like a vaccum lock. Tried cold and heat but it just snaps shut when it approahes the top thread. Help!

The top came apart, how do I put it back together? I can see how the grooves match but it doesn't stay in. Am I missing a trick to twisting the two cap pieces together?

Will this fit in most cup holders and in my water bottle holder on my bike? Or is it too wide? Will it make the bike ride to work without spilling?

I know that the cap is dishwasher safe, but is the actual flask dishwasher safe too?
