My son really likes his Tumbler. Great quality and the ice last for a long time. He's in the National Guard so this is perfect for him to take to drill. I'm glad I paid the additional cost to add his initials. Well worth the money!
I am a big fan of the 30 ounce IceFlow. It is so easy to carry and drink from. I decided to try the larger version to have more water. It does need the oversized drink cup in the car. It is also more difficult to pick up for drinking ( maybe my hands are just small). These were the things I was looking for in a review so hopefully this is helpful. It’s still durable and drinks well, but I prefer the 30 ounce.
I replaced my 32 oz version which I accidentally left at an auto repair place. I figured I’d go a bit larger to have enough water for my longer work outs. Water with ice stays cold for a long time. I’d say the 40 oz is a bit heavy, but no real problem. You can’t go wrong with either version.
I have been usually it daily especially for work. I love that it’s spill free, so I can just chuck it in my work bag without worrying about getting water everywhere. I also like how the spout can fold down and not constantly open and exposed. Lastly, it does awesome at keeping my water cold.
