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!

After doing my research and reading multiple reviewing stating that Stanley cups were the best at keeping any drink cold for hours and keeping your ice for longer I decided to purchase the Ice flow flip straw, 64oz jug. But to my disappointment this jug did not measure up. After only 3 hours I noticed that all of the ice would be fully melted. I thought, maybe it the shape of the ice so I tried different shaped of ice and filling the jug with more ice than water but I always got the same result, melted ice. I don't know if I got a deflected item but I am very disappointed. The jug is also extremely heavy. I have purchased different water bottles and this by far has been one of the worst.

I love my 64oz flip straw Ice flow jug! Me and my hubby love them so much we got 2 each different colors of course... we carry it every day, to the gym, church, shopping, our second one we brought for each other is for our long trips traveling! You have to invest in this jug, this little baby stay cold (all) day and ice 🧊 last me 2 to 3 days but really hard ice up to 2 days! That 3 day still ice and cold drinks but ice still strong but trying to melt! But water are drink still cold! You rock Stanley💪🏾💯❤

Love this jug. Attributes are obvious - big enough for a day’s worth of Slurpee-style drink and keeps it icy for the entire day. The large mouth makes loading with ice or cleaning up easy.

But there’s a couple of design issues I think can be remedied:

1. It needs an old-style ‘lay flat’ handle built into the body. This made the old ‘work buddy’ bottles easy to hang on to in an upright position, or pour from, or drink from, all with one hand. The newer handles just stick out too far when not in use, so bring back the old design and apply it here. The top carry handle is nice, but I do worry that it will eventually cause the lid to fail.

2. An alternate lid. One that has no openings, will not leak, and insulates better. Or maybe one with a small screw top attached to the latest of the lid, so you could tip back and guzzle from, or stick a straw in if you like to vary your drinking behavior. Or both! They could be sold separately or other options. I just dislike the flip straw lid. Eventually it leaks, and is the weakest part of this product.

Food for thought. And on that note, I’m going to fill up my jug to go with it.
