I LOVE this tumbler! I fill it daily with ice then add my protein drink. It keeps my drink very cold all day and the ice slowly melts so I get water the rest of the day. The flip top is great for ensuring no spills and staying clean. The next morning there is still about a cup of ice in the tumbler! I gave only 4 stars because the straw is initially difficult to use with ice - the ice gets stuck to the sides and it is hard to insert the straw because of this. I've tried inserting the straw before adding ice, and the ice won't move so the straw comes off the grommet on the lid when twisting the lid on. I also would love a stainless steel straw option. None of these are game changers for me. I'd buy another in a heartbeat!

I replaced a cheap knock off brand one with the real Stanley tumbler & I love them so much!! Best purchase I’ve made all year. I got 2 of the blue/pink swirl patterned, 30 oz. models. They’re so pretty that I had to show them off a little bit🤭. I almost went with next size up, but I’m glad I didn’t. This size fits perfectly in my purse so I can take it everywhere. I honestly don’t know how I made it through the day without them. I noticed that since I got them, I now drink mostly water. I only occasionally have juice or a soda. I’ve recommended these to a couple of my coworkers & they did say that they will definitely go with a Stanley (with the awesome flip straw) when their current one breaks down. I’ll look forward to seeing what designs you come up with next. Thank you Stanley!!

After going back and forth between the 40oz and the 64oz for some time, I’m ultimately glad that I decided to go with this size. I’ve now been using this water jug for a little over a month and have been extremely pleased by its quality and how long it keeps your drinks cold. I filled it up prior to a weekend camping trip Friday morning and by Sunday evening after replenishing some water it still had a very good amount of ice left in it. This water jug has also been great for my job because I work long shifts at a warehouse and it’s been very helpful to have extra water throughout the day. Prior to purchasing I read some negative reviews that it leaks and complaints of buyers receiving the wrong size or color but I didn’t experience any of that. Overall very very happy with my new water jug!

Quality:built to last
Performance:sippy works without straw
Appearance:very aesthetically pleasing

Seller was great with super fast delivery! Delivered one day earlier than anticipated
Well packaged
The cap is very sturdy and hardy
Can use without straw
Do note that it is heavier than Hydro flask, those new to Stanley. Pros and cons of different brands. One big pro is wide mouth = easy washing without bottle brush
Recommend getting a cup sleeve for the bottom to avoid scratches as it came with slight scratch at the bottom probably from general packing and moving.
